For a finite undirected graph G on n vertices some continuous optimizationproblems taken over the n-dimensional cube are presented and it is provedthat their optimum values equal the independence number of G.Keywords: graph, independence.1991 Mathematical Subject Classification: 05C35.1 Introduction and ResultsLet G be a finite simple and undirected graph on V (G) = f1; 2; :::; ng with itsedge set E(G). A subset I of V (G), such that the subgraph of G induced by Iis edgeless, is...
