The spatial pheromone signal for ant colony optimisation

Abstract

The effect of the passive insecticide on the ant colony Monomorius pharaonis is localised with minor losses - only one ant. The information on the insecticide location is transferred through the colony in all directions with great speed. After deserting the basic trail, a rapid consolidation of the new ant colony is probably established by the spatial pheromone signal. A simulation model for the time calculation and the number of ants necessary for the formation of the shortest way between the nest and the fictive food source was formed. The basic ant performances have a prevailing part in the shortest trail formation and those are: the range of the radius pheromone signal and the intensity of the pheromone trail evaporation. © 2009 Springer Berlin Heidelberg.
