[0034] The present invention will be further explained below in conjunction with the accompanying drawings.
[0035]The Conjunctive Normal Form (CNF) representation of the Boolean satisfiability problem (SAT) is composed of strings line by line, such as figure 1 As shown in , each line represents a disjunctive item (clause), the number separated by spaces in the line is the number of the proposition variable (variable), and the number 0 at the end of the line is a newline placeholder. When constructing a graph structure, each propositional variable is regarded as a node of the graph. It should be noted that the normal form and its logical non-form of the same propositional variable represent different nodes respectively. If any two different variables appear in the same disjunction item at the same time, an edge is made between these two nodes. In addition, if a variable has two states, an edge is also required between these two nodes side to describe this relationship. Two ...
