Graph Imperfection II.

Abstract:

The imperfection ratio is a graph invariant which indicates how good a lower bound the weighted clique number gives on the weighted chromatic number, in the limit as weights get large. Its introduction was motivated by investigations of the radio channel assignment problem, where one has to assign channels to transmitters and the demands for channels at some transmitters are large. In this paper we show that the imperfection ratio behaves multiplicatively under taking the lexicographic produc...
