Final Update: October 26, 2022
This repository is no longer supported or updated. There is a more extensive repository of Sports Scheduling instances and results at RobinX. The Traveling Tournament Problem also appears there. There is a github backup available at https://github.com/Robin-X/RobinX. Thanks to avid van Bulck for taking this over.
Thank you to all those who have submitted results in the past! I am very glad that the Traveling Tournament Problem and all of its variants have proven to be a useful testing ground for optimization approaches. Michael Trick
