Fundp07 TRANSP-OR TALK Bierlaire, Michel Thémans, Michaël Zufferey, Nicolas A heuristic for global nonlinear optimization 2007 Séminaire du Groupe de Recherche sur les Transports FUNDP - Université de Namur, Namur, Belgium April 25, 2007 The proposed heuristic combines a variable neighborhood search (VNS) framework with a local search performed by a trust-region algorithm. The curvature of the function is exploited to generate the neighborhoods. Numerical results illustrate an excellent behavior of the method compared to recent heuristics proposed in the literature.
