New SAT solver based on finding satisfiable 2-SAT sub problem

Satisfiability(SAT) problem is one of the NP-Hard problems.This paper introduced a new SAT solver called FSSAT.This SAT solver solved the problem by searching a satisfiable 2-SAT sub problem.SAT was NP-complete,but it can be solved in linear time when the given formula contains only binary clauses(2-SAT).BinSat(2-SAT solver) was used to solve the 2-SAT sub problem and improved the 2-SAT sub problem according to the truth assignment.The experimental results show that the solver outperforms UnitWalk.
