The particle swarm optimization (PSO) has been widely used to solve continuous problems. The discrete problems have just begun to be also solved by the discrete PSO. However, the combinatorial problems remain a prohibitive area to the PSO mainly in case of integer values. In this paper, we propose a combinatorial PSO (CPSO) algorithm that we take up(More)
In general, the multi-mode resource-constrained project scheduling problem (MRCPSP) is considered as mono-objective problem which aims at finishing the project as soon as possible under resource constraints. Nevertheless, the MRCPSP is multi-objective by nature and the omission of this aspect in its resolution may biases the reality; so we think extend the(More)
