Detailed Description

A SAT solver that is an implementation of Algorithm D from Knuth's The Art of Computer Programming Volume 4: Satisfiability, Fascicle 6.

It is based on the Davis-Putnam-Logemann-Loveland (DPLL) algorithm [1], keeps references to a single "watched" literal per clause, and uses a set of "active" variables for unit propagation.
