nissy/src/utils.c, branch master Where is nissy? https://git.tronto.net/nissy/atom?h=master 2023-05-01T14:33:51Z Split nissy in other repos, see README.md 2023-05-01T14:33:51Z Sebastiano Tronto sebastiano@tronto.net 2023-05-01T14:33:51Z urn:sha1:bf44088d4373a9520e860152c56a958332819c4b Symcoord version of nissy. Interesting idea, but performance are 2022-09-06T16:00:40Z Sebastiano Tronto sebastiano@tronto.net 2022-09-06T16:00:40Z urn:sha1:a125e69c8ce0a2764b1e50b2dad0a4fa9d141ef4 actually slower. AT THIS STAGE NISSY IS NOT USABLE. Faster optimal solver. 2021-12-13T19:40:18Z Sebastiano Tronto sebastiano.tronto@gmail.com 2021-12-13T19:40:18Z urn:sha1:1215648b1ba3c592bd9d97b871349673d1702e44 This is a pretty big one, but unfortunately performance only improved by about 5%. I implemented one of the main ideas of nxopt, that is switching to the inverse scramble on the fly if it gives a lower branching factor. On the one hand it makes sense that it does not have such a huge impact, since it only rarely happens that we do have a lower branching factor on inverse, but on the other hand I am quite sad that the improvement is barely noticeable :-( Maybe the problem is that I have introduced a lot of new overhead and I can improve that in the future. Or maybe I am just overlooking something stupid.
