[13], and further developed in Lemar´echal and Oustry [9], leads to simple alternative derivations of well-known, important relaxations to two well-known problems of discrete optimization: the maximum stable set problem and the maximum vertex cover problem. The resulting relaxation is easily transformed to the well-known Lov´asz θ number.EnglishLagrange dualityLovász theta functionSemi-definite relaxationStable setConstraint theoryLinear programmingOptimizationProblem solvingVirtual realityLagrange dualityLovasz theta functionSemidefinite relaxationStable setsLagrange multipliersA derivation of Lovász' theta via augmented lagrange dualityArticle10.1051/ro:20030121290-3868
