PHast – Perfect Hashing made fast
2026 Proceedings of the SIAM Symposium on Algorithm Engineering and Experiments (ALENEX), pages 1-14, January 2026, doi: 10.1137/1.9781611978957.1
The paper introduces PHast, (minimal) perfect hash function that combines the fastest available queries, very fast construction (especially PHast+ variant), and good space consumption (below 2 bits per key).
