The isin-DANTE method is an hybrid meta-heuristic. In combines the evolutionary ant colony optimization (ACO) algorithms with a limited depth search. This depth search is based in the pheromone trails used by the ACO, which allows it to be oriented to the more promising areas of the search space. Some results are presented for the multiple...

The NP multiple criteria minimum spanning tree as several applications into the network design problems. In this paper, we rst introduce some properties than can help to characterize the problem, as well as to produce heuristics to solve it in a more e cient way. In the second part, we propose an application of the Multiple Objective Network...

In this paper we present an Ant Colony Optimisation based algorithm to determine the Pareto set for the Multiple Objective Travelling Salesman Problem. Our results are then compared with the ones obtained with a genetic algorithm.

The ϵ-Depth ANT Explorer (ϵ- DANTE ) algorithm applied to a multiple objective optimization problem is presented in this paper. This method is a hybridization of the ant colony optimization algorithm with a depth search procedure, putting together an oriented/limited depth search. A particular design of the pheromone set of rules is suggested...

The Ant Colony Optimisation Algorithm (ACO) supports the development of a system for a multi-objective network optimisation problem. The ACO system bases itself on an agent's population and, in this case, uses a multi-level pheromone trail associated to a cost vector, which will be optimised.

We study the hydrodynamic limit for a model of symmetric exclusion processes with long jumps heavy-tailed and in contact with infinitely extended reservoirs. We show how the corresponding hydrodynamic equations are affected by the parameters defining the model. The hydrodynamic equations are characterized by a class of super-diffusive operators...
