A vertex cover in a graph is a set of vertices that includes at least one endpoint of every edge, and a vertex cover is minimum if no other vertex cover has fewer vertices. A matching in a graph is a set of edges no two of which share an endpoint, and a matching is maximum if no other matching has more edges.. It is obvious from the definition that any …

SpletNP-Completeness. Module 6 focuses on the concept of NP-Completeness, which is a fundamental concept in theoretical computer science that deals with the complexity of solving problems. The module begins with a review of polynomial time and polynomial-time verification, which are concepts related to the efficiency of algorithms in solving problems. http://www.cs.bme.hu/~dmarx/papers/planar-edge-prext.pdf

It is shown that the determination of B2( G) for arbitrary G is NP-complete. Essentially the same proof can be used in showing the NP-completeness of minimizing If I over all embeddings
