State cook's theorem

WebCook’s Theorem states that Any NP problem can be converted to SAT in polynomial time. In order to prove this, we require a uniform way of representing NP problems.

WebCook's Theorem SATis NP-complete. Proof:We have to do 2 things: Prove that SATbelongs to NP; Show that for anydecision problem fin NP: f<=pSAT: i.e. be transformed into an instance F(x)of SATsuch that f(x)=1 iff SAT (F(x))=1. That (a) holds has already been shown. Now let fbe any decision problemin NP.
