WebThe CNF transformation, in the worse case, can result in a normal form that is exponentially larger than the input formula. To avoid this blow up, we can introduce new variables in the transformation. This idea, originally due to Tseitin (1968), results in CNF which is linear in size of the original input. WebThe conversion algorithm used is very simple and does not perform any optimizations. In many cases the optimized converters like the Tseitin transformation would give a much smaller output much faster.
