WebbApplying pre- and inprocessing techniques to simplify CNF formulas both before and during search can considerably improve the performance of modern SAT solvers. These algorithms mostly aim at arXiv:1310.4756v1 [cs.LO] 17 Oct 2013 reducing the number of clauses, literals, and variables in the formula. WebbThen click on the Convert menu, then click on Transform Grammar. Now, there are four steps that we have to go through in order to transform the grammar into CNF. They are removing lambda, unit, and useless productions, followed by a final step. Each step will be discussed in the following sections. Remove Lambda Productions
