چکیده

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 that assigns actual teams to numbers in the pattern. The procedure is implemented using the nite domain library of the constraint logic programming language ECL i PS e. Experimental results show that, in practical cases, the optimal solution can be found in reasonable time, despite the fact that the problem is NP-complete. Note: This work has been partly carried out while the author was visiting CWI as an ERCIM fellow. Work carried out under project PNA1.2, CIP.

Constraint-based Round Robin Tournament Planning

Sport tournament planning becomes a complex task in the presence of heterogeneous requirements from teams, media, fans and other parties. Existing approaches to sport tournament planning often rely on precomputed tournament schemes which may be too rigid to cater for these requirements. Existing work on sport tournaments suggests a separation of the planning process into three phases. In this w...

Minimizing Breaks in Sport Scheduling with Local Search

Sport scheduling has received significant attention in the recent years and has contributed many challenging applications for optimization technologies. This paper reconsiders the problem of minimizing the number of breaks in round-robin tournaments, an application which has been recently tackled by sophisticated constraint and mathematical programming approaches. It proposes a simulated anneal...

An Integrated Constraint Programming Approach to Scheduling Sports Leagues with Divisional and Round-Robin Tournaments

Previous approaches for scheduling a league with round-robin and divisional tournaments involved decomposing the problem into easier subproblems. This approach, used to schedule the top Swedish handball league Elitserien, reduces the problem complexity but can result in suboptimal schedules. This paper presents an integrated constraint programming model that allows to perform the scheduling in ...
