A new way of constructing (minimal) perfect hash functions is described. The technique considerably reduces the overhead associated with resolving buckets in two-level hashing schemes. Two memory probes suffice for evaluation of the function. This improves the probe performance of previous minimal perfect hashing schemes, and is shown to be optimal.
