Web1 jun. 1975 · We show that the problem of finding an optimal schedule for a set of jobs is NP-complete even in the following two restricted cases. o (1) All jobs require one time unit. (2) All jobs require one or two time units, and there are only two processor resolving (in the negative a conjecture of R. L. Graham, Proc. SJCC, 1972, pp. 205–218). As a … Web5 jan. 2024 · NP-Hard Problem: A Problem X is NP-Hard if there is an NP-Complete problem Y, such that Y is reducible to X in polynomial time. NP-Hard problems are as hard as NP-Complete problems. NP-Hard Problem need not be in NP class. If every problem of NP can be polynomial time reduced to it called as NP Hard. A lot of times takes the …
NP-completeness - Wikipedia
WebSince all NP problems can be reduced to NPC problem, so long as any one NPC problem found a polynomial algorithm, then all the NP problem can be solved with this algorithm, NP is equal to P. So it's amazing to find a polynomial algorithm for NPC. Therefore, former Wencai said, "It is the NPC problem that makes people believe in P≠NP."

When the answer is yes, it can be demonstrated to be yes through the existence of a short (polynomial length) solution. qct couplings
