Abstract

Analyzing the behavior of stochastic procedures is generally recognized to be relevant. A possible way for doing so consists in observing the exploration performed. A formalization in this sense is proposed here: A method for studying this aspect regardless the type of approach used is defined and tested. The consequent measure of exploration is applied to MAX---MIN Ant System: The impact of the values of the parameters on the exploration is assessed. The conclusions drawn are put in relation with the indications provided by the average *** -branching factor.
