,Improved Construction Heuristics and Iterated?Local Search for the Routing and Wavelength Assignmen random instances. We analyze the properties of several instances in detail and propose an improved construction heuristic to handle ‘problematic’ instances. Our iterated local search finds the optimum for most instances.

Improving Metaheuristic Performance by Evolving a Variable Fitness Function,ple objectives can be defined through evolutionary changes in the search direction. We show that the VFF significantly improves performance of constructive and VNS approaches on training problems, and “l(fā)earn” problem features which enhance the performance on unseen test problem instances.

Efficient Local Search Limitation Strategies for Vehicle Routing Problems, routing problem deals with the assignment of a set of transportation orders to a fleet of vehicles, and the sequencing of stops for each vehicle to minimize transportation costs. The examined strategies are applied to three standard neighborhoods and implemented in a recently suggested powerful mem
