Traveling Tournament Scheduling: A Systematic Evaluation of Simulated Annealling [chapter]

Pascal Van Hentenryck, Yannis Vergados
2006 Lecture Notes in Computer Science  
The main technical contribution underlying these results is a number of compositive neighborhood moves that aggregate sequences of existing moves; these novel moves preserve the mirroring or distance structure  ...  In particular, the algorithm matches or improves most bestknown solutions and produces numerous new best solutions spread over all classes of problems.  ...  The algorithm in [6] works for single round-robin schedules but a double round-robin schedule can be obtained by a simple mirroring.  ...

A Parallel Simulated Annealing Approach for the Mirrored Traveling Tournament Problem [article]

Vijay Menon, Saurabh Jha
2013 arXiv   pre-print
The Traveling Tournament Problem (TTP) is a benchmark problem in sports scheduling and has been extensively studied in recent years.  ...  In this paper we test a parallel simulated annealing approach for solving the mTTP using OpenMP on shared memory systems and we found that this approach is superior especially with respect to the number  ...  While arriving at an optimized schedule, S, for the double round robin tournament, TTP places two additional constraints on the schedule called the AtMost and the NonRepeat constraint.  ...
