E-mail: markus.waibel@epfl.ch Few people with an interest in biological system modelling have never heard of Ant Colony Optimization (ACO). It is the single, most well-known example of what has come to be called "bio-inspired" algorithms, and one of the most impressive success stories of translating biological phenomena into engineering solutions. The interest of Aco lies in its simplicity and versatility: It has been successfully applied to problems as diverse as network routing, industrial scheduling in metal casting and logistics with a nonhomogeneous fleet of trucks. In spite of ACO's huge success and its relevance to many fields outside computer science, up to now know-how of this field has been spread out over many scientific publications without an…
