We are given a set A = {a1, . . . , an}, a collection B1, B2, . . . , Bm of subsets of A, and an non-negative integer k. We are asked: is there a hitting set H ⊆ A for B1, B2, . . . , Bm so that the size of H is at most k? Prove that the Hitting Set problem is NP-complete

Webb11 okt. 2016 · intersects (hits) every set in . If we regard as de ning a hypergraph on V (where each set in consti-tuting a hyperedge) then we see that the hitting set problem is equivalent to the vertex cover problem on hypergraphs; this problem is NP-hard. Here we will show two simple algorithms for nding reasonably small hitting sets. Theorem 1.1. … Webb9 maj 2011 · That is, if you can solve Hampath, then you can solve every NP problem, since every NP problem can be polynomially reduced to 3 -SAT by Cook-Levin. Second, it still remains to show that Hampath is in fact NP itself. Third, a very naïve answer to 1. is: SAT is more general than 3 -SAT, so it should be harder to reduce SAT to something than to ...
