Other applications: edge covering, vertex cover Interesting example: IBM finds computer viruses (wikipedia) … WebThis was expected, set cover is an NP-hard problem. We don’t expect that an LP can characterize an NP-hard problem (why?). So, the LP value is not equal to the ILP value. Can we at least get an approximate solution of set cover using this LP? Lov asz gave a randomized algorithm for set-cover with approximation factor of O(log(jUj)). The idea was: WebShow that the Minimum Dominating Set problem is NP-Hard. You may assume for this question that all graphs are connected. Solution: We will reduce the Minimum Set Cover problem to the Minimum Dominating Set problem.
