I am pleased to announce that the instances for our competitions are now available for download. Furthermore, we have successfully implemented the solution upload functionality. However, please note that the verification process for submitted solutions will commence in a few weeks' time.
Presenting our latest example instances! Your feedback was invaluable, and we've responded accordingly. The example file has been revamped—say goodbye to pesky tiny objects in instances. Plus, a new generator has been included! And that's not all – we've also introduced visualizations for the new instances.
First batch of example instances for the new CGSHOP2024 challenge! You can find it on the corresponding page under the download button. Please note that this is just the first batch and we are still experimenting with generators. We may publish a further batch of example instances once we have …
With ~24 hours to go (27th, AoE), please note that the rank is only final, after we evaluated all submissions. If you encounter any problems with your upload, please just mail us a hash of it and then forward us the submission via some link. We will then add it …
Due to an update of the infrastructure, we had an unexpected long downtime of some hours today. There may be some further short (few minutes) downtimes the next days, as we do some further updates.
We are happy to announce the Fifth Computational Geometry Challenge, as part of CG Week in Dallas, TX, USA, June 12-15, 2023. As in previous years, the objective will be to compute good solutions to instances of a difficult geometric optimization problem. The specific problem chosen for the …
Call for Problems
Since 2019, the Computational Geometry Challenge has been part of CG Week. The objective is to compute good solutions for instances of a challenging geometric optimization problem. The contributors with the most outstanding solutions are recognized at CG Week and invited to present their results, both at …
The winners of the 2022 Challenge will present their approach at SoCG, Thursday, June 09, 15:30-16:30 CET. See the full program.
