Examples 42: dual problems vocabulary: primal: the original problem, usually a minimize lpp in sec 42 dual: a related but opposite problem with the same answer, usually a standard maximize lpp in sec 42. On a set of np-hard problems such as maxcut [10], sparsest cut [1, 4], and bal-anced separator [4] arora et al extended the primal-dual lp algorithm to the sdp. The last table, being both dual feasible and primal feasible, is the nal table for our problem: the optimal solution of (1) is x 1 = 6=5, x 2 = 2=5, x 3 = 1 we have accused the dual simplex method of being \nothing but a disguised simpex method working on the dual.
