NP-completeness theory
NP-completeness theory is a branch of computational complexity theory that deals with a certain class of decision problems called NP-complete problems. These problems have the property that if there exists a polynomial-time algorithm to solve any one of them, then there exists a polynomial-time algorithm to solve all problems in the complexity class NP (nondeterministic…
