A conference schedule optimizer using mixed integer linear programming. This is used to generate the schedule for Electromagnetic Field events.
You'll need the COIN-OR CBC solver installed to use this library.
apt-get install coinor-cbc or brew tap coin-or-tools/coinor && brew install cbc.
The original concept and code for this library is from David MacIver. For more information on this approach, see David's talk Easy solutions to hard problems from PyCon UK 2016.
A similar library with a slightly different approach is conference-scheduler.
