2026-01-12Improve performance of H48 solver with prefetchingSebastiano Tronto4-134/+259
With this commit we re-structure how the node expansion in the H48 solution search works to allow prefetching of pruning values, showing performance improvements in the range of 30-45% on x86, depending on table size and solution length. A small bug fix related to appending solutions is included in this commit.

2025-12-19Minor improvementSebastiano Tronto1-2/+7
Add a trivial check to H48 solver. The benchmarks show, surprisingly, a more noticeable improvement for larger solvers (h10, h11). I was expecting it to be more noticeable for smaller solvers. It is likely that this change is irrelevant to performance and all changes in the benchmark results are just random chance.

2025-11-24Fix duplicate solutions, overflow in maxsols and improve symmetry reduction ↵Sebastiano Tronto5-118/+203
for H48. This commit fixes two bugs: - A bug that caused duplicates solutions for symmetric scrambles. - An overflow in the maxsols parameter for the H48 solver, which caused it to find much fewer solutions than existed. Moreover, the H48 solvers has been improved by reducing by symmetry not only from the starting position, but also up to the first 4 moves.
