I read the cnf format file.. but how to express this expression in .cnf file? i get confused when there is a conjunction inside the paranthesis and how to express --> and <-> ? please help me
Solution
There are a couple of solutions.
Limboole is an open source tool which I believe includes a separate 'propositional logic to CNF' converter.
More generally, you could also use a tool that supports propositional logic natively; some examples include Z3, CVC3, and Yices.
