Abstract: The variables of backdoors are key decision variables to guide the search for SAT problems, and which optimize SAT problem solving and therefore become the one of the hot spots for artificial intelligence direction. This paper studies some problems of the backdoors of SAT problems, analyzes the concept of backdoors and classification of backdoors, proposes the factor of impact backdoors size solving, discusses the relationship of the parameters complexity of backdoors and problem difficulty comprehensively.

Key word: propositional satisfiability problem; backdoors; problem class; parameters complexity;problem difficulty
