New Instances and Scoring System Released
We have expanded the benchmark set to 250 planar triangulation instances. Along with the original 201 small and medium instances, 49 large instances have now been added in response to community feedback.
We have also released the updated scoring system, which will differ slightly from previous years to better reward both exact methods on smaller instances and scalable heuristics on larger ones.
You can find all resources on the project page. We are looking forward to your submissions.

Thank you all, and keep up the good work!
