Test 64-bit integers for pribality. Miller-Rabin, Lucas. BPSW
The code here tests 64-bit integers for primality. For 32-bit values it uses hashing and then a single Miller-Rabin test. As values get larger it uses up to two more Miller Rabin rounds, and at the end it uses BPSW (which is one rould of Miller Rabin and then one of Lucas). Compared to other codes that achieve the same I believe that the hash tables used here are compact, and both the programs and the intermediate data used to create them are provided. ...
FFP (Feature frequency profile) is an alignment free comparison tool for phylogenetic analysis and text comparison. It can be applied to nucleotide sequences, complete genomes, proteomes and even used for text comparison.
Provides efficient, effective implementations of 32- and 64-bit hash functions based on Rabin fingerprints / irreducible polynomials, in Java. Also provides integration with java.security.MessageDigest API.
