In this paper, we discussed CNF-SAT problem (NP-Complete problem) and analysis two solutions that can solve the problem, the PL-Resolution algorithm and the WalkSAT algorithm. PL-Resolution is a sound and complete algorithm that can be used to determine satisfiability and unsatisfiability with ce...
Years and Authors of Summarized Original Work 1998; Hirsch 2003; Schuler Problem Definition The satisfiability problem ( SAT ) for Boolean formulas in conjunctive normal form ( CNF ) is one of the first NP -complete problems [ 2 , 13 ]. Since its NP -completeness currently leaves no hope ...
