Test Sets for Vertex Cover Problems

open access: yesElectronic Notes in Discrete Mathematics, 1999
Abstract We describe the structure of the unique minimal test set T for a family of vertex cover problems. The set T corresponds to the Grobner basis of the binomial ideal for the problem as described in [1]. While T has a surprisingly simple structure, in particular when the underlying graph is complete, it is N P -complete to decide whether ...
