Centrum Voor Wiskunde En Informatica Scheduling Sport Tournaments Using Constraint Logic Programming Scheduling Sport Tournaments Using Constraint Logic Programming

We tackle the problem of scheduling the matches of a round robin tournament for a sport league. We formally deene the problem, state its computational complexity, and present a solution algorithm using a two-step approach. The rst step is the creation of a tournament pattern and is based on known graph-theoretic results. The second one is a constraint-based depth-rst branch and bound procedure ...
