Alg. Dev. 4 shows that subpopulation’s sensitivity, with various pheromone sensitivity levels, influenced pozitively the solutions of TSP. 67 and the degrees of freedom are 5. 05. After t-test is performed the Wilcoxon signedrank test [14]. The result is W = 21. 05, showing that exists a significant difference between the compared algorithms. 6 Conclusions A technique called Sensitive Ant Model (SAM) that combines stigmergic communication and heterogeneous agent behavior is developed and tested.

In [24] exploration was introduced only from an intuitive point of view. It was intended as the distribution of solutions in promising areas of the search space. This interpretation may be seen as the distribution of solutions inside clusters. The analysis of this fact may be object of future research, but nothing appears to be really in contrast with this experimental analysis. 6 Conclusions In this paper a definition of the exploration of the search space performed by a stochastic algorithm is proposed.
