X Title: NP-Complete Problem -- from Wolfram MathWorld

Description: A problem which is both NP (verifiable in nondeterministic polynomial time) and NP-hard (any NP-problem can be translated into this problem). Examples of NP-hard problems include the Hamiltonian cycle and traveling salesman problems. In a landmark paper, Karp (1972) showed that 21 intractable combinatorial computational problems are all NP-complete.
