## A Python library of approval-based committee (ABC) rules
**A**pproval-**b**ased **c**ommittee rules (ABC rules) are voting methods for selecting a committee, i.e., a fixed-size subset of candidates.
ABC rules are also known as approval-based multi-winner rules.
The input of such rules are
[approval ballots](https://en.wikipedia.org/wiki/Approval_voting#/media/File:Approval_ballot.svg).
We recommend the book
([Multi-Winner Voting with Approval Preferences](https://arxiv.org/abs/2007.01795))
by Lackner and Skowron [2] as a detailed introduction to ABC rules and related research directions.
In addition, the
[survey by Faliszewski et al.](http://research.illc.uva.nl/COST-IC1205/BookDocs/Chapters/TrendsCOMSOC-02.pdf) [1]
is useful as a more general introduction to committee voting (not limited to approval ballots).
The following ABC rules are implemented:
* Approval Voting (AV)
* Satisfaction Approval Voting (SAV)
* Proportional Approval Voting (PAV)
* Sequential Proportional Approval Voting (seq-PAV)
* Reverse Sequential Proportional Approval Voting (revseq-PAV)
* Approval Chamberlin-Courant (CC)
* Phragmén's sequential rule
* Monroe's rule
* Minimax Approval Voting (MAV)
* Greedy Monroe
* Method of Equal Shares (Rule X)
* Phragmén's First Method (Eneström's Method)
* and many more ...
In addition, one can verify axiomatic properties such as
* Justified Representation (JR)
* Propotional Justified Representation (PJR)
* Extended Justified Representation (EJR)
* Priceability
* The core property
## Installation
As simple as:
```bash
pip install abcvoting
```
Further details can be found [here](https://abcvoting.readthedocs.io/en/latest/installation.html).
## Development
Install all dependencies including development requirements and the abcvoting package in
[development mode](https://setuptools.readthedocs.io/en/latest/userguide/development_mode.html):
```bash
pip install -e .[dev]
```
Basic unit tests can be run by excluding tests which require additional dependencies:
```bash
pytest -m "not mipgurobi and not gmpy2 and not slow" tests/
```
For development, configure the black formatter and pre-commit hooks - see below. Also installing
all optional dependencies is recommended.
A development package is build for every commit on the master branch and uploaded to the test
instance of PyPI. It can be installed using the following command:
```bash
python3 -m pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple abcvoting
```
### Black formatting
Code needs to be formatted using the [black formatter](https://black.readthedocs.io/en/stable/). This is
checked by Github actions.
[Configure your editor](https://black.readthedocs.io/en/stable/integrations/editors.html) to run the
black formatter.
### Pre-commit hooks
Pre-commit hooks are not required, but they are recommended for development.
[Pre-commit](https://pre-commit.com/) is used to manage and maintain pre-commit hooks. Install
pre-commit (e.g. via apt, conda or pip) and then run `$ pre-commit install` to install the hooks.
