Mapel-elections

This pacakge is a plugin for mapel extending it with capabilities of drawing maps of various elections intances.

For the most recent version of mapel, visit its git repo.

Installation

For a simple installation, type: pip install mapel-elections in the console.

For more complicated variants of installation, refer to the readme of mapel here.

Extra dependencies

For the full functionality of the package, it is recommended to also install extra dependencies. Doing this is covered in this readme. The extra dependencies contain:

cplex>=20.1.0.1
pulp~=2.5.1
abcvoting~=2.0.0b0
permanent

which unlock approval based committee rules (which require solving I(L)P programs) and sampling a matrix using a permanent-based approach.

One can do it by invoking
pip install mapel-elections[extras]

:exclamation: Note that this library contains C++ extensions. So installing this library from sources might be a bit cumbersome. We will, one day, put here an instruction how to do it.

Testing Installation

If the instalation was successfull, you should be able to mimic the following:

(<virtual_envirnonment_name>) $ python
...
>>> import mapel.elections.metrics.cppdistances as d
...
>>> d.swapd([[0,1,2],[0,1,2]], [[0,1,2],[2,1,0]])
3
>>> exit()
