In computational complexity theory,a computational problem H is called NP-hard if,for every problem L which can be solved in non-deterministic polynomial-time,there is a polynomial-time reduction from L to H. That is,assuming a solution for H takes 1 unit time,H's solution can be used to solve L in polynomial time. As a consequence,finding a polynomial time algorithm to solve a single NP-hard problem would give polynomial time algorithms for all the problems in the complexity class NP. As it is suspected,but unproven,that P≠NP,it is unlikely that any polynomial-time algorithms for NP-hard problems exist.
