not really, depends on the evaporation rate of the pheromone. If you increase the evaporation co-efficient it's more suited to a dynamic environment

It's much more nuanced than that though. Increasing the evaporation rate also makes exploitation much harder, not to mention that the positive feedback cycle on previously very good edges can take a long time to dissipate.

ACO for dynamic environments generally require much more attention to how the problem is applied to the environment or the generation of a more hybrid approach.
