WebThe Cook–Levin theorem states that the Boolean satisfiability problem is NP-complete, thus establishing that such problems do exist. In 1972, Richard Karp proved that several other problems were also NP-complete (see Karp's 21 NP-complete problems ); thus, there is a class of NP-complete problems (besides the Boolean satisfiability problem).
