Chaff is an algorithm for solving instances of the Boolean satisfiability problem in programming.
Some available implementations of the algorithm in software are mChaff and zChaff, the latter one being the most widely known and used.
zChaff was originally written by Dr. Lintao Zhang, now[clarify] at Microsoft Research, hence the “z”.
It is now maintained by researchers at Princeton University and available for download as both source code and binaries on Linux.
