Journées de l'optimisation 2007 Optimizations days

Ant Colony Optimization (ACO) is now over 15 years old. During these years several – not to say many – researchers have contributed to the field. Some contributions kept close contact with the original natural metaphor, some were more mathematically oriented; some contributions were small variations of the original ant system, some departed much from it; some contributions considered only combinatorial optimization problems, some extended by much the spectrum of possible applications; some contributions were primarily of academic interest, some made their way to the market. This tutorial will focus on the latter of each mentioned pair.
