The HapChat algorithm is an alternative MEC solver able to handle higher coverages. It can be used through “whatshap phase –algorithm=hapchat”. It has been described in this paper:

Stefano Beretta, Murray Patterson, Simone Zaccaria, Gianluca Della Vedova, Paola Bonizzoni.
HapCHAT: adaptive haplotype assembly for efficiently leveraging high coverage in long reads.
BMC Bioinformatics, 19:252, 2018.

A parallelization of the core dynamic programming algorithm (“pWhatsHap”) has been described in

M. Aldinucci, A. Bracciali, T. Marschall, M. Patterson, N. Pisanti, M. Torquati.
High-Performance Haplotype Assembly
Proceedings of the 11th International Meeting on Computational Intelligence Methods for Bioinformatics and Biostatistics (CIBB), 245-258, 2015.

pWhatsHap is currently not integrated into the main WhatsHap source code. It is available in branch parallel in the Git repository.
