Résumé:
In this thesis, we propose an approximate optimization of an ant colony that
depends on swarm intelligence, in order to solve one of the combinatorial optimization problems which is the multi-objective peddler problem, using the populationbased ant colony (PACO) algorithm, which uses a population in addition to a
traditional pheromone matrix, after So we used PACO with Crowding Population
Replacement Scheme in order to increase the efficiency and effectiveness of the
research.
