We propose a novel approach for data clustering based on sequential multi-objective multi-act games (ClusSMOG). It automatically determines the number of clusters and optimises simultaneously the inertia and the connectivi-ty objectives. The approach consists of three structured steps. The first step identifies initial clusters and calculates a set of(More)
In this paper, we are concerned with a nondifferentiable multiobjective programming problem with inequality constraints. We introduce four new classes of generalized convex functions by combining the concepts of weak strictly pseudoinvex, strong pseudoinvex, weak quasi invex, weak pseudoinvex and strong quasi invex functions in Aghezzaf and Hachimi [Numer.(More)
Providing a long term security of a computer system requires an efficient management of the resources consumption. This is particularly true for the Mobile Ad-hoc NETworks (MANETs) where nodes are characterized by limited resources. In this paper, we propose a game theoretic framework to predict malicious behaviors within a MANET and to analyze the best(More)
