Meta-heuristic algorithms have been effectively employed to tackle a wide range of optimisation issues, including structural engineering challenges. The the shape and size large-scale truss structures is difficult due nonlinear interplay between cross-sectional nodal coordinate pressures structures. Recently, it was demonstrated that newly proposed Marine Predator Algorithm (MPA) performs very ...

Résumé en anglais Hill-climbing constitutes one of the simplest way to produce approximate solutions of a combinatorial optimization problem, and is a central component of most advanced metaheuristics. This paper focuses on evaluating climbing techniques in a context where deteriorating moves are not allowed, in order to isolate the intensification aspect of metaheuristics. We aim at providing ...

One of the basic problems of user on manual wheelchair is overcoming architectural barriers (kerbs, stairs etc.) on its way. Even though many research studies have been reported in different fields to increase the independence of wheelchair users, the question of overcoming obstacles by a wheelchair always remains as topic of discussion for many researchers. In this paper, the author has propos...

Parallel algorithms based on stochastic hill-climbing and parallel algorithms based on simple elements of a genetic algorithm for the one-sided bipartite crossing number problem, used in row-based vlsi layout, were investigated. These algorithms were run on a pvm cluster. The experiments show that the parallel approach does not bring faster computation but it does, however, much more importantl...
