## [1.0 UNRELEASED]
|
||||
|
||||
Version 1.0 introduced multiple changes, especially on the `Simulation` class and anything related to how configuration is handled.
|
||||
For an explanation of the general changes in version 1.0, please refer to the file `docs/notes_v1.0.rst`.
|
||||
|
||||
### Added
|
||||
* A modular set of classes for environments/models. Now the ability to configure the agents through an agent definition and a topology through a network configuration is split into two classes (`soil.agents.BaseEnvironment` for agents, `soil.agents.NetworkEnvironment` to add topology).
|
||||
* Environments now have a class method to make them easier to use without a simulation`.run`. Notice that this is different from `run_model`, which is an instance method.
|
||||
* Ability to run simulations using mesa models
|
||||
* The `soil.exporters` module to export the results of datacollectors (`model.datacollector`) into files at the end of trials/simulations
|
||||
* Agents can now have generators as a step function or a state. They work similar to normal functions, with one caveat in the case of `FSM`: only `time` values (or None) can be yielded, not a state. This is because the state will not change, it will be resumed after the yield, at the appropriate time. The return value *can* be a state, or a `(state, time)` tuple, just like in normal states.
|
||||
* Simulations can now specify a `matrix` with possible values for every simulation parameter. The final parameters will be calculated based on the `parameters` used and a cartesian product (i.e., all possible combinations) of each parameter.
|
||||
* Simple debugging capabilities in `soil.debugging`, with a custom `pdb.Debugger` subclass that exposes commands to list agents and their status and set breakpoints on states (for FSM agents). Try it with `soil --debug <simulation file>`
|
||||
### Changed
|
||||
* Configuration schema (`Simulation`) is very simplified. All simulations should be checked
|
||||
* Model / environment variables are expected (but not enforced) to be a single value. This is done to more closely align with mesa
|
||||
* `Exporter.iteration_end` now takes two parameters: `env` (same as before) and `params` (specific parameters for this environment). We considered including a `parameters` attribute in the environment, but this would not be compatible with mesa.
|
||||
* `num_trials` renamed to `iterations`
|
||||
* General renaming of `trial` to `iteration`, to work better with `mesa`
|
||||
* `model_parameters` renamed to `parameters` in simulation
|
||||
* Simulation results for every iteration of a simulation with the same name are stored in a single `sqlite` database
|
||||
|
||||
### Removed
|
||||
* Any `tsih` and `History` integration in the main classes. To record the state of environments/agents, just use a datacollector. In some cases this may be slower or consume more memory than the previous system. However, few cases actually used the full potential of the history, and it came at the cost of unnecessary complexity and worse performance for the majority of cases.

# [SOIL](https://github.com/gsi-upm/soil)
|
||||
|
||||
|
||||
Soil is an extensible and user-friendly Agent-based Social Simulator for Social Networks.
|
||||
Learn how to run your own simulations with our [documentation](http://soilsim.readthedocs.io).
|
||||
|
||||
Follow our [tutorial](examples/tutorial/soil_tutorial.ipynb) to develop your own agent models.
|
||||
|
||||
> **Warning**
|
||||
> Soil 1.0 introduced many fundamental changes. Check the [documention on how to update your simulations to work with newer versions](docs/notes_v1.0.rst)
|
||||
|
||||
## Features
|
||||
|
||||
* Integration with (social) networks (through `networkx`)
|
||||
* Convenience functions and methods to easily assign agents to your model (and optionally to its network):
|
||||
* Following a given distribution (e.g., 2 agents of type `Foo`, 10% of the network should be agents of type `Bar`)
|
||||
* Based on the topology of the network
|
||||
* **Several types of abstractions for agents**:
|
||||
* Finite state machine, where methods can be turned into a state
|
||||
* Network agents, which have convenience methods to access the model's topology
|
||||
* Generator-based agents, whose state is paused though a `yield` and resumed on the next step
|
||||
* **Reporting and data collection**:
|
||||
* Soil models include data collection and record some data by default (# of agents, state of each agent, etc.)
|
||||
* All data collected are exported by default to a SQLite database and a description file
|
||||
* Options to export to other formats, such as CSV, or defining your own exporters
|
||||
* A summary of the data collected is shown in the command line, for easy inspection
|
||||
* **An event-based scheduler**
|
||||
* Agents can be explicit about when their next time/step should be, and not all agents run in every step. This avoids unnecessary computation.
|
||||
* Time intervals between each step are flexible.
|
||||
* There are primitives to specify when the next execution of an agent should be (or conditions)
|
||||
* **Actor-inspired** message-passing
|
||||
* A simulation runner (`soil.Simulation`) that can:
|
||||
* Run models in parallel
|
||||
* Save results to different formats
|
||||
* Simulation configuration files
|
||||
* A command line interface (`soil`), to quickly run simulations with different parameters
|
||||
* An integrated debugger (`soil --debug`) with custom functions to print agent states and break at specific states
|
||||
|
||||
## Mesa compatibility
|
||||
|
||||
SOIL has been redesigned to integrate well with [Mesa](https://github.com/projectmesa/mesa).
|
||||
For instance, it should be possible to run a `mesa.Model` models using a `soil.Simulation` and the `soil` CLI, or to integrate the `soil.TimedActivation` scheduler on a `mesa.Model`.
|
||||
|
||||
Note that some combinations of `mesa` and `soil` components, while technically possible, are much less useful or might yield surprising results.
|
||||
For instance, you may add any `soil.agent` agent on a regular `mesa.Model` with a vanilla scheduler from `mesa.time`.
|
||||
But in that case the agents will not get any of the advanced event-based scheduling, and most agent behaviors that depend on that may not work.
|
||||
|
||||
|
||||
## Changes in version 0.3
|
||||
|
||||
Version 0.3 came packed with many changes to provide much better integration with MESA.
|
||||
For a long time, we tried to keep soil backwards-compatible, but it turned out to be a big endeavour and the resulting code was less readable.
|
||||
This translates to harder maintenance and a worse experience for newcomers.
|
||||
In the end, we decided to make some breaking changes.
|
||||
|
||||
If you have an older Soil simulation, you have two options:
|
||||
|
||||
* Update the necessary configuration files and code. You may use the examples in the `examples` folder for reference, as well as the documentation.
|
||||
* Keep using a previous `soil` version.

## Mesa compatibility
|
||||
|
||||
Soil is in the process of becoming fully compatible with MESA.
|
||||
As of this writing,
|
||||
|
||||
This is a non-exhaustive list of tasks to achieve compatibility:
|
||||
|
||||
* Environments.agents and mesa.Agent.agents are not the same. env is a property, and it only takes into account network and environment agents. Might rename environment_agents to other_agents or sth like that
|
||||
- [ ] Integrate `soil.Simulation` with mesa's runners:
|
||||
- [ ] `soil.Simulation` could mimic/become a `mesa.batchrunner`
|
||||
- [ ] Integrate `soil.Environment` with `mesa.Model`:
|
||||
- [x] `Soil.Environment` inherits from `mesa.Model`
|
||||
- [x] `Soil.Environment` includes a Mesa-like Scheduler (see the `soil.time` module.
|
||||
- [ ] Integrate `soil.Agent` with `mesa.Agent`:
|
||||
- [x] Rename agent.id to unique_id?
|
||||
- [x] mesa agents can be used in soil simulations (see `examples/mesa`)
|
||||
- [ ] Document the new APIs and usage

|
||||
Configuring a simulation
|
||||
------------------------
|
||||
|
||||
There are two ways to configure a simulation: programmatically and with a configuration file.
|
||||
In both cases, the parameters used are the same.
|
||||
The advantage of a configuration file is that it is a clean declarative description, and it makes it easier to reproduce.
|
||||
|
||||
Simulation configuration files can be formatted in ``json`` or ``yaml`` and they define all the parameters of a simulation.
|
||||
Here's an example (``example.yml``).
|
||||
|
||||
.. literalinclude:: example.yml
|
||||
:language: yaml
|
||||
|
||||
|
||||
This example configuration will run three trials (``num_trials``) of a simulation containing a randomly generated network (``network_params``).
|
||||
The 100 nodes in the network will be SISaModel agents (``network_agents.agent_type``), which is an agent behavior that is included in Soil.
|
||||
10% of the agents (``weight=1``) will start in the content state, 10% in the discontent state, and the remaining 80% (``weight=8``) in the neutral state.
|
||||
All agents will have access to the environment (``environment_params``), which only contains one variable, ``prob_infected``.
|
||||
The state of the agents will be updated every 2 seconds (``interval``).
|
||||
|
||||
Now run the simulation with the command line tool:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
soil example.yml
|
||||
|
||||
Once the simulation finishes, its results will be stored in a folder named ``MyExampleSimulation``.
|
||||
Three types of objects are saved by default: a pickle of the simulation; a ``YAML`` representation of the simulation (which can be used to re-launch it); and for every trial, a ``sqlite`` file with the content of the state of every network node and the environment parameters at every step of the simulation.
|
||||
|
||||
|
||||
.. code::
|
||||
|
||||
soil_output
|
||||
└── MyExampleSimulation
|
||||
├── MyExampleSimulation.dumped.yml
|
||||
├── MyExampleSimulation.simulation.pickle
|
||||
├── MyExampleSimulation_trial_0.db.sqlite
|
||||
├── MyExampleSimulation_trial_1.db.sqlite
|
||||
└── MyExampleSimulation_trial_2.db.sqlite
|
||||
|
||||
|
||||
You may also ask soil to export the states in a ``csv`` file, and the network in gephi format (``gexf``).
|
||||
|
||||
Network
|
||||
=======
|
||||
|
||||
The network topology for the simulation can be loaded from an existing network file or generated with one of the random network generation methods from networkx.
|
||||
|
||||
Loading a network
|
||||
#################
|
||||
|
||||
To load an existing network, specify its path in the configuration:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
---
|
||||
network_params:
|
||||
path: /tmp/mynetwork.gexf
|
||||
|
||||
Soil will try to guess what networkx method to use to read the file based on its extension.
|
||||
However, we only test using ``gexf`` files.
|
||||
|
||||
For simple networks, you may also include them in the configuration itself using , using the ``topology`` parameter like so:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
---
|
||||
topology:
|
||||
nodes:
|
||||
- id: First
|
||||
- id: Second
|
||||
links:
|
||||
- source: First
|
||||
target: Second
|
||||
|
||||
|
||||
Generating a random network
|
||||
###########################
|
||||
|
||||
To generate a random network using one of networkx's built-in methods, specify the `graph generation algorithm <https://networkx.github.io/documentation/development/reference/generators.html>`_ and other parameters.
|
||||
For example, the following configuration is equivalent to :code:`nx.complete_graph(n=100)`:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
network_params:
|
||||
generator: complete_graph
|
||||
n: 100
|
||||
|
||||
Environment
|
||||
============
|
||||
The environment is the place where the shared state of the simulation is stored.
|
||||
For instance, the probability of disease outbreak.
|
||||
The configuration file may specify the initial value of the environment parameters:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
environment_params:
|
||||
daily_probability_of_earthquake: 0.001
|
||||
number_of_earthquakes: 0
|
||||
|
||||
All agents have access to the environment parameters.
|
||||
|
||||
In some scenarios, it is useful to have a custom environment, to provide additional methods or to control the way agents update environment state.
|
||||
For example, if our agents play the lottery, the environment could provide a method to decide whether the agent wins, instead of leaving it to the agent.
|
||||
|
||||
|
||||
Agents
|
||||
======
|
||||
Agents are a way of modelling behavior.
|
||||
Agents can be characterized with two variables: agent type (``agent_type``) and state.
|
||||
Only one agent is executed at a time (generally, every ``interval`` seconds), and it has access to its state and the environment parameters.
|
||||
Through the environment, it can access the network topology and the state of other agents.
|
||||
|
||||
There are three three types of agents according to how they are added to the simulation: network agents and environment agent.
|
||||
|
||||
Network Agents
|
||||
##############
|
||||
Network agents are attached to a node in the topology.
|
||||
The configuration file allows you to specify how agents will be mapped to topology nodes.
|
||||
|
||||
The simplest way is to specify a single type of agent.
|
||||
Hence, every node in the network will be associated to an agent of that type.
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
agent_type: SISaModel
|
||||
|
||||
It is also possible to add more than one type of agent to the simulation, and to control the ratio of each type (using the ``weight`` property).
|
||||
For instance, with following configuration, it is five times more likely for a node to be assigned a CounterModel type than a SISaModel type.
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
network_agents:
|
||||
- agent_type: SISaModel
|
||||
weight: 1
|
||||
- agent_type: CounterModel
|
||||
weight: 5
|
||||
|
||||
The third option is to specify the type of agent on the node itself, e.g.:
|
||||
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
topology:
|
||||
nodes:
|
||||
- id: first
|
||||
agent_type: BaseAgent
|
||||
states:
|
||||
first:
|
||||
agent_type: SISaModel
|
||||
|
||||
|
||||
This would also work with a randomly generated network:
|
||||
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
network:
|
||||
generator: complete
|
||||
n: 5
|
||||
agent_type: BaseAgent
|
||||
states:
|
||||
- agent_type: SISaModel
|
||||
|
||||
|
||||
|
||||
In addition to agent type, you may add a custom initial state to the distribution.
|
||||
This is very useful to add the same agent type with different states.
|
||||
e.g., to populate the network with SISaModel, roughly 10% of them with a discontent state:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
network_agents:
|
||||
- agent_type: SISaModel
|
||||
weight: 9
|
||||
state:
|
||||
id: neutral
|
||||
- agent_type: SISaModel
|
||||
weight: 1
|
||||
state:
|
||||
id: discontent
|
||||
|
||||
Lastly, the configuration may include initial state for one or more nodes.
|
||||
For instance, to add a state for the two nodes in this configuration:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
agent_type: SISaModel
|
||||
network:
|
||||
generator: complete_graph
|
||||
n: 2
|
||||
states:
|
||||
- id: content
|
||||
- id: discontent
|
||||
|
||||
|
||||
Or to add state only to specific nodes (by ``id``).
|
||||
For example, to apply special skills to Linux Torvalds in a simulation:
|
||||
|
||||
.. literalinclude:: ../examples/torvalds.yml
|
||||
:language: yaml
|
||||
|
||||
|
||||
Environment Agents
|
||||
##################
|
||||
In addition to network agents, more agents can be added to the simulation.
|
||||
These agents are programmed in much the same way as network agents, the only difference is that they will not be assigned to network nodes.
|
||||
|
||||
|
||||
.. code::
|
||||
|
||||
environment_agents:
|
||||
- agent_type: MyAgent
|
||||
state:
|
||||
mood: happy
|
||||
- agent_type: DummyAgent
|
||||
|
||||
|
||||
You may use environment agents to model events that a normal agent cannot control, such as natural disasters or chance.
|
||||
They are also useful to add behavior that has little to do with the network and the interactions within that network.
|
||||
|
||||
Templating
|
||||
==========
|
||||
|
||||
Sometimes, it is useful to parameterize a simulation and run it over a range of values in order to compare each run and measure the effect of those parameters in the simulation.
|
||||
For instance, you may want to run a simulation with different agent distributions.
|
||||
|
||||
This can be done in Soil using **templates**.
|
||||
A template is a configuration where some of the values are specified with a variable.
|
||||
e.g., ``weight: "{{ var1 }}"`` instead of ``weight: 1``.
|
||||
There are two types of variables, depending on how their values are decided:
|
||||
|
||||
* Fixed. A list of values is provided, and a new simulation is run for each possible value. If more than a variable is given, a new simulation will be run per combination of values.
|
||||
* Bounded/Sampled. The bounds of the variable are provided, along with a sampler method, which will be used to compute all the configuration combinations.
|
||||
|
||||
When fixed and bounded variables are mixed, Soil generates a new configuration per combination of fixed values and bounded values.
|
||||
|
||||
Here is an example with a single fixed variable and two bounded variable:
|
||||
|
||||

Mesa compatibility
|
||||
------------------
|
||||
|
||||
Soil is in the process of becoming fully compatible with MESA.
|
||||
The idea is to provide a set of modular classes and functions that extend the functionality of mesa, whilst staying compatible.
|
||||
In the end, it should be possible to add regular mesa agents to a soil simulation, or use a soil agent within a mesa simulation/model.
|
||||
|
||||
This is a non-exhaustive list of tasks to achieve compatibility:
|
||||
|
||||
- [ ] Integrate `soil.Simulation` with mesa's runners:
|
||||
- [ ] `soil.Simulation` could mimic/become a `mesa.batchrunner`
|
||||
- [ ] Integrate `soil.Environment` with `mesa.Model`:
|
||||
- [x] `Soil.Environment` inherits from `mesa.Model`
|
||||
- [x] `Soil.Environment` includes a Mesa-like Scheduler (see the `soil.time` module.
|
||||
- [ ] Allow for `mesa.Model` to be used in a simulation.
|
||||
- [ ] Integrate `soil.Agent` with `mesa.Agent`:
|
||||
- [x] Rename agent.id to unique_id?
|
||||
- [x] mesa agents can be used in soil simulations (see `examples/mesa`)
|
||||
- [ ] Provide examples
|
||||
- [ ] Using mesa modules in a soil simulation

What are the main changes in version 1.0?
|
||||
#########################################
|
||||
|
||||
Version 1.0 is a major rewrite of the Soil system, focused on simplifying the API, aligning it with Mesa, and making it easier to use.
|
||||
Unfortunately, this comes at the cost of backwards compatibility.
|
||||
|
||||
We drew several lessons from the previous version of Soil, and tried to address them in this version.
|
||||
Mainly:
|
||||
|
||||
- The split between simulation configuration and simulation code was overly complicated for most use cases. As a result, most users ended up reusing configuration.
|
||||
- Storing **all** the simulation data in a database is costly and unnecessary for most use cases. For most use cases, only a handful of variables need to be stored. This fits nicely with Mesa's data collection system.
|
||||
- The API was too complex, and it was difficult to understand how to use it.
|
||||
- Most parts of the API were not aligned with Mesa, which made it difficult to use Mesa's features or to integrate Soil modules with Mesa code, especially for newcomers.
|
||||
- Many parts of the API were tightly coupled, which made it difficult to find bugs, test the system and add new features.
|
||||
|
||||
The 0.30 rewrite should provide a middle ground between Soil's opinionated approach and Mesa's flexibility.
|
||||
The new Soil is less configuration-centric.
|
||||
It aims to provide more modular and convenient functions, most of which can be used in vanilla Mesa.
|
||||
|
||||
How are agents assigned to nodes in the network
|
||||
###############################################
|
||||
|
||||
The constructor of the `NetworkAgent` class has two arguments: `node_id` and `topology`.
|
||||
If `topology` is not provided, it will default to `self.model.topology`.
|
||||
This assignment might err if the model does not have a `topology` attribute, but most Soil environments derive from `NetworkEnvironment`, so they include a topology by default.
|
||||
If `node_id` is not provided, a random node will be selected from the topology, until a node with no agent is found.
|
||||
Then, the `node_id` of that node is assigned to the agent.
|
||||
If no node with no agent is found, a new node is automatically added to the topology.
|
||||
|
||||
|
||||
Can Soil environments include more than one network / topology?
|
||||
###############################################################
|
||||
|
||||
Yes, but each network has to be included manually.
|
||||
Somewhere between 0.20 and 0.30 we included the ability to include multiple networks, but it was deemed too complex and was removed.

Quickstart
|
||||
----------
|
||||
|
||||
This section shows how to run your first simulation with Soil.
|
||||
For installation instructions, see :doc:`installation`.
|
||||
|
||||
There are mainly two parts in a simulation: agent classes and simulation configuration.
|
||||
An agent class defines how the agent will behave throughout the simulation.
|
||||
The configuration includes things such as number of agents to use and their type, network topology to use, etc.
|
||||
|
||||
|
||||
.. image:: soil.png
|
||||
:width: 80%
|
||||
:align: center
|
||||
|
||||
|
||||
Soil includes several agent classes in the ``soil.agents`` module, and we will use them in this quickstart.
|
||||
If you are interested in developing your own agents classes, see :doc:`soil_tutorial`.
|
||||
|
||||
Configuration
|
||||
=============
|
||||
To get you started, we will use this configuration (:download:`download the file <quickstart.yml>` directly):
|
||||
|
||||
.. literalinclude:: quickstart.yml
|
||||
:language: yaml
|
||||
|
||||
The agent type used, SISa, is a very simple model.
|
||||
It only has three states (neutral, content and discontent),
|
||||
Its parameters are the probabilities to change from one state to another, either spontaneously or because of contagion from neighboring agents.
|
||||
|
||||
Running the simulation
|
||||
======================
|
||||
|
||||
To see the simulation in action, simply point soil to the configuration, and tell it to store the graph and the history of agent states and environment parameters at every point.
|
||||
|
||||
.. code::
|
||||
|
||||
❯ soil --graph --csv quickstart.yml [13:35:29]
|
||||
INFO:soil:Using config(s): quickstart
|
||||
INFO:soil:Dumping results to soil_output/quickstart : ['csv', 'gexf']
|
||||
INFO:soil:Starting simulation quickstart at 13:35:30.
|
||||

|
||||
INFO:soil:Finished Simulation quickstart trial 0 at 13:35:49 in 19.43677067756653 seconds
|
||||
INFO:soil:Starting Dumping simulation quickstart trial 0 at 13:35:49.
|
||||
INFO:soil:Finished Dumping simulation quickstart trial 0 at 13:35:51 in 1.7733407020568848 seconds
|
||||
INFO:soil:Dumping results to soil_output/quickstart
|
||||
INFO:soil:Finished simulation quickstart at 13:35:51 in 21.29862952232361 seconds
|
||||
|
||||
|
||||
The ``CSV`` file should look like this:
|
||||
|
||||
.. code::
|
||||
|
||||
agent_id,t_step,key,value
|
||||
env,0,neutral_discontent_spon_prob,0.05
|
||||
env,0,neutral_discontent_infected_prob,0.1
|
||||
env,0,neutral_content_spon_prob,0.2
|
||||
env,0,neutral_content_infected_prob,0.4
|
||||
env,0,discontent_neutral,0.2
|
||||
env,0,discontent_content,0.05
|
||||
env,0,content_discontent,0.05
|
||||
env,0,variance_d_c,0.05
|
||||
env,0,variance_c_d,0.1
|
||||
|
||||
Results and visualization
|
||||
=========================
|
||||
|
||||
The environment variables are marked as ``agent_id`` env.
|
||||
Th exported values are only stored when they change.
|
||||
To find out how to get every key and value at every point in the simulation, check out the :doc:`soil_tutorial`.
|
||||
|
||||
The dynamic graph is exported as a .gexf file which could be visualized with
|
||||
`Gephi <https://gephi.org/users/download/>`__.
|
||||
Now it is your turn to experiment with the simulation.
|
||||
Change some of the parameters, such as the number of agents, the probability of becoming content, or the type of network, and see how the results change.
|
||||
|
||||
|
||||
Soil also includes a web server that allows you to upload your simulations, change parameters, and visualize the results, including a timeline of the network.
|
||||
To make it work, you have to install soil like this:
|
||||
|
||||
.. code::

||||

### MESA
|
||||
|
||||
Starting with version 0.3, Soil has been redesigned to complement Mesa, while remaining compatible with it.
|
||||
That means that every component in Soil (i.e., Models, Environments, etc.) can be mixed with existing mesa components.
|
||||
In fact, there are examples that show how that integration may be used, in the `examples/mesa` folder in the repository.
|
||||
|
||||
Here are some reasons to use Soil instead of plain mesa:
|
||||
|
||||
- Less boilerplate for common scenarios (by some definitions of common)
|
||||
- Functions to automatically populate a topology with an agent distribution (i.e., different ratios of agent class and state)
|
||||
- The `soil.Simulation` class allows you to run multiple instances of the same experiment (i.e., multiple trials with the same parameters but a different randomness seed)
|
||||
- Reporting functions that aggregate multiple

This example can be run like with command-line options, like this:
|
||||
|
||||
```bash
|
||||
python cars.py --level DEBUG -e summary --csv
|
||||
#or
|
||||
soil cars.py -e summary
|
||||
```
|
||||
|
||||
This will set the `CSV` (save the agent and model data to a CSV) and `summary` (print the a summary of the data to stdout) exporters, and set the log level to DEBUG.

"""
|

This is an example of a simplified city, where there are Passengers and Drivers that can take those passengers
|
||||
from their location to their desired location.
|
||||
|
||||
An example scenario could play like the following:
|
||||
|
||||
- Drivers start in the `wandering` state, where they wander around the city until they have been assigned a journey
|
||||
- Passenger(1) tells every driver that it wants to request a Journey.
|
||||
- Each driver receives the request.
|
||||
If Driver(2) is interested in providing the Journey, it asks Passenger(1) to confirm that it accepts Driver(2)'s request
|
||||
- When Passenger(1) accepts the request, two things happen:
|
||||
- Passenger(1) changes its state to `driving_home`
|
||||
- Driver(2) starts moving towards the origin of the Journey
|
||||
- Once Driver(2) reaches the origin, it starts moving itself and Passenger(1) to the destination of the Journey
|
||||
- When Driver(2) reaches the destination (carrying Passenger(1) along):
|
||||
- Driver(2) starts wondering again
|
||||
- Passenger(1) dies, and is removed from the simulation
|
||||
- If there are no more passengers available in the simulation, Drivers die

There are two similar implementations of this simulation.
|
||||
|
||||
- `basic`. Using simple primites
|
||||
- `improved`. Using more advanced features such as the `time` module to avoid unnecessary computations (i.e., skip steps), and generator functions.
|
||||
|
||||
The examples can be run directly in the terminal, and they accept command like arguments.
|
||||
For example, to enable the CSV exporter and the Summary exporter, while setting `max_time` to `100` and `seed` to `CustomSeed`:
|
||||
|
||||
```
|
||||
python rabbit_agents.py --set max_time=100 --csv -e summary --set 'seed="CustomSeed"'
|
||||
```
|
||||
|
||||
To learn more about how this functionality works, check out the `soil.easy` function.

class Simulation:

"""
|
||||
Similar to nsim.NetworkSimulation with three main differences:
|
||||
1) agent type can be specified by name or by class.
|
||||
2) instead of just one type, a network agents distribution can be used.
|
||||
The distribution specifies the weight (or probability) of each
|
||||
agent type in the topology. This is an example distribution: ::
|
||||
|
||||
[
|
||||
{'agent_type': 'agent_type_1',
|
||||
'weight': 0.2,
|
||||
'state': {
|
||||
'id': 0
|
||||
}
|
||||
},
|
||||
{'agent_type': 'agent_type_2',
|
||||
'weight': 0.8,
|
||||
'state': {
|
||||
'id': 1
|
||||
}
|
||||
}
|
||||
]
|
||||
|
||||
In this example, 20% of the nodes will be marked as type
|
||||
'agent_type_1'.
|
||||
3) if no initial state is given, each node's state will be set
|
||||
to `{'id': 0}`.
|
||||
|
||||
Parameters
|
||||
---------
|
||||

|
||||
Default type of NetworkAgent to use for nodes not specified in network_agents
|
||||

|
||||
whose value indicates the state
|
||||

|
||||
Directory path to load simulation assets (files, modules...)
|
||||
seed : str, optional
|
||||
Seed to use for the random generator

|
||||
Similar to network_agents. Distribution of Agents that control the environment
|
||||
environment_class: soil.environment.Environment subclass, optional
|
||||
Class for the environment. It defailts to soil.environment.Environment
|
||||
load_module : str, module name, deprecated
|
||||
If specified, soil will load the content of this module under 'soil.agents.custom'
|
||||
|
||||
A simulation is a collection of agents and a model. It is responsible for running the model and agents, and collecting data from them.
|
||||
|
||||
Args:
|
||||
version: The version of the simulation. This is used to determine how to load the simulation.
|
||||
name: The name of the simulation.
|
||||
description: A description of the simulation.
|
||||
group: The group that the simulation belongs to.
|
||||
model: The model to use for the simulation. This can be a string or a class.
|
||||
parameters: The parameters to pass to the model.
|
||||
matrix: A matrix of values for each parameter.
|
||||
seed: The seed to use for the simulation.
|
||||
dir_path: The directory path to use for the simulation.
|
||||
max_time: The maximum time to run the simulation.
|
||||
max_steps: The maximum number of steps to run the simulation.
|
||||
interval: The interval to use for the simulation.
|
||||
iterations: The number of iterations (times) to run the simulation.
|
||||
num_processes: The number of processes to use for the simulation. If greater than one, simulations will be performed in parallel. This may make debugging and error handling difficult.
|
||||
tables: The tables to use in the simulation datacollector
|
||||
agent_reporters: The agent reporters to use in the datacollector
|
||||
model_reporters: The model reporters to use in the datacollector
|
||||
dry_run: Whether or not to run the simulation. If True, the simulation will not be run.
|
||||
backup: Whether or not to backup the simulation. If True, the simulation files will be backed up to a different directory.
|
||||
overwrite: Whether or not to replace existing simulation data.
|
||||
source_file: Python file to use to find additional classes.
