Analysis of the best-worst ant system and its variants on the TSP

Oscar Cordón García, Iñaki Fernández de Viana, Francisco Herrera Triguero


In this contribution, we will study the influence of the three main
components of Best-Worst Ant System: the best-worst pheromone
trail update rule, the pheromone trail mutation and the restart. Both the
importance of each of them and the fact whether all of them are necessary will
be analyzed. The performance of different variants of this algorithm will be
tested when solving different instances of the TSP.
