Improve performance of H48 solver with prefetching 2026-01-12T17:09:43Z Sebastiano Tronto sebastiano@tronto.net 2026-01-12T17:09:43Z urn:sha1:9a013b7c68f94e6be0fe8748c9012a441fe0273f 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.
