a few weeks. This include mainly three things: 1. Various tweaks for a total performance gain of around 30%. 2. Take into account symmetries and avoid repeated work. This required a re-work of the splitting into tasks before the solve. 3. Add a second fallback table (eoesep). This gives huge performance gains for particular scrambles (e.g. superflip). After merging this commit, remove and re-generate all pruning tables.

2024-10-04Table-based transformations (will revert immediately)Sebastiano Tronto4-40/+115
This commit changes transformations to being based on a lookup table intead of a big switch. This is something I had planned for a long time and the code is nicer with this change. But unfortunately the performance is noticeably worse, so I'll revert all these changes in the next commit. I wanted to push this anyway so we can keep track of this.
2024-09-07Improved gendata_h48k2 performanceSebastiano Tronto1-2/+2
Performance for the "real coordinate" case (h0) is ok, but still around 3x slower than the gendata_h48k4 method. Performance for the intermediate tables is not good, but for now I'll keep it like this. This also shows that for h11 we should use the gendata_h48k4 method for h11. For intermediate table, h8, h9 and h10 might be too slow to compute in an acceptable time. We could restrict to h7 (largest with base = 9).
