The traditional min-cut problem involves finding a cut with minimum weight between two specified vertices. The planar multiway cut problem is a NP-hard generalization of the min-cut problem. It involves separating a weighted planar graph with k specified vertices into k components such that the tota
Although this may seem a paradox, all exact science is dominated by the idea of approximation. Bertrand Russell (1872-1970) Most natural optimization problems, including those arising in important application areas, are NP-hard. Therefore, under the widely believed conΒ jecture that P -=/= NP, their
We compare three lower bounds for the minimum cardinality of a multiway cut in a graph separating a given set S of terminals. The main result is a relatively short algorithmic proof for a simplified version of a min-max theorem of the first and the third authors asserting that the best of the three
