Simplify cnf
WebbI am having serious problems whenever I try to convert a formula to CNF/DNF. My main problem is that I do not know how to simplify the formula in the end, so even though I apply the rules in a correct way and reach the end of the question, being unable to simplify (absorb etc.) and get the correct result kills me. WebbDeveloping simplification using Z3. In the following we outline a procedure for extracting a simplified CNF representation of a formula. Extract subset of atoms used to satisfy the negation of a formula. evaluate each atom in fml using m and create literals corresponding to the sign of the evaluation.
