Table of Contents Possible speedup? BBHash Limasset et al. (2017) uses multiple layers to create a minimal perfect hashing functions (MPFH), that hashes some input set into \([n]\). (See also my note on PTHash (Pibiri and Trani 2021).) Simply said, it maps the \(n\) elements into \([\gamma \cdot n]\) using hashing function \(h_0\). The \(k_0\) elements that have collisions are mapped into \([\gamma \cdot k_0]\) using \(h_1\). Then, the \(k_1\) elements with collisions are mapped into \([\gamm...
