Kicker Scheduling

This software is to generate kicker playing schedules that should be as fair as possible.

There are the following hard constraints:
- Each match consists of 4 players, with 2 teams of 2 players each.
- All players participating at the whole schedule will be included in the same number of matches.

The following optimization objectives are being regarded:
- Each player should be scheduled for each table position equally often.
- All combinations of team-mates should happen equally often.
- All combinations of opponent players should happen equally often.
- The leisure times of each players between its participated matches should be distributed as equally as possible.
