Client–server and cost effective sets in graphs
For any integer , a set of vertices of a graph is -cost-effective if for every . In this paper we study the minimum cardinality of a maximal -cost-effective set and the maximum cardinality of a -cost-effective set. We obtain Gallai-type results involving the -cost-effective and global -offensive all...
