Construction and improvement algorithms for dispersion problems

Aringhieri, Roberto; Cordone, Roberto; Grosso, Andrea - In: European Journal of Operational Research 242 (2015) 1, pp. 21-33

Given a set N, a pairwise distance function d and an integer number m, the Dispersion Problems (DPs) require to extract from N a subset M of cardinality m, so as to optimize a suitable function of the distances between the elements in M. Different functions give rise to a whole family of...

Using SVM to combine global heuristics for the Standard Quadratic Problem

Dellepiane, Umberto; Palagi, Laura - In: European Journal of Operational Research 241 (2015) 3, pp. 596-605

The Standard Quadratic Problem (StQP) is an NP-hard problem with many local minimizers (stationary points). In the literature, heuristics based on unconstrained continuous non-convex formulations have been proposed (Bomze & Palagi, 2005; Bomze, Grippo, & Palagi, 2012) but none dominates the other in...
