Given an undirected graph with weights on the vertices, the maximum weight clique problem (MWCP) is to find a subset of mutually adjacent vertices (i.e., a clique) having the largest total weight. This is a generalization of the classical problem of finding the maximum cardinality clique of an unweighted graph, which arises as a special case of the MWCP(More)
This article addresses the area of decision making for information systems (IS). We recognize the great demand for methods and techniques that can be of practical help by presenting a new, conceptual approach, the profile distance method, to support the IS selection problem. This approach combines the merits of two prominent concepts individually applied in(More)
