Axelrod
=======
A library with the following principles and goals:
1. Enabling the reproduction of previous Iterated Prisoner's Dilemma research
as easily as possible.
2. Creating the de-facto tool for future Iterated Prisoner's Dilemma
research.
3. Providing as simple a means as possible for anyone to define and contribute
new and original Iterated Prisoner's Dilemma strategies.
4. Emphasizing readability along with an open and welcoming community that
is accommodating for developers and researchers of a variety of skill levels
Currently the library contains well over 100 strategies and can perform a
variety of tournament types (RoundRobin, Noisy, Spatially-distributed, and
probabilistically ending) and population dynamics while taking advantage
of multi-core processors.
**Please contribute via pull request (or just get in touch with us).**
For an overview of how to use and contribute to this repository, see the
documentation: http://axelrod.readthedocs.org/
If you do use this library for your personal research we would love to hear
about it: please do add a link at the bottom of this README file (PR's welcome
or again, just let us know) :) If there is something that is missing in this
library and that you would like implemented so as to be able to carry out a
project please open an issue and let us know!
Installation
============
The simplest way to install is::
$ pip install axelrod
Otherwise::
$ git clone https://github.com/Axelrod-Python/Axelrod.git
$ cd Axelrod
$ python setup.py install
Note that on Ubuntu `some
users <https://github.com/Axelrod-Python/Axelrod/issues/309>`_ have had problems
installing matplotlib. This seems to help with that::
sudo apt-get install libfreetype6-dev
sudo apt-get install libpng12-0-dev
Usage
-----
The full documentation can be found here:
`axelrod.readthedocs.org/ <http://axelrod.readthedocs.org/>`__.
The documentation includes details of how to setup a tournament but here is an
example showing how to create a tournament with all stochastic strategies::
import axelrod
strategies = [s() for s in axelrod.ordinary_strategies if s().classifier['stochastic']]
tournament = axelrod.Tournament(strategies)
results = tournament.play()
The :code:`results` object now contains all the results we could need::
print(results.ranked_names)
gives::
['Meta Hunter', 'Inverse', 'Forgetful Fool Me Once', 'GTFT: 0.33', 'Champion', 'ZD-GTFT-2', 'Eatherley', 'Math Constant Hunter', 'Random Hunter', 'Soft Joss: 0.9', 'Meta Majority', 'Nice Average Copier', 'Feld', 'Meta Minority', 'Grofman', 'Stochastic WSLS', 'ZD-Extort-2', 'Tullock', 'Joss: 0.9', 'Arrogant QLearner', 'Average Copier', 'Cautious QLearner', 'Hesitant QLearner', 'Risky QLearner', 'Random: 0.5', 'Meta Winner']
There is also a `notebooks repository
<https://github.com/Axelrod-Python/Axelrod-notebooks>`_ which shows further
examples of using the library.
Results
=======
A tournament with the full set of strategies from the library can be found at
https://github.com/Axelrod-Python/tournament. These results can be easily viewed
at http://axelrod-tournament.readthedocs.org.
