    Thema: Mathematik , Wirtschaftswissenschaften
    Notizen: Abstract The Ant System is a distributed metaheuristic that combines an adaptive memory with alocal heuristic function to repeatedly construct solutions of hard combinatorial optimizationproblems. In this paper, we present an improved ant system algorithm for the Vehicle RoutingProblem with one central depot and identical vehicles. Computational results on fourteenbenchmark problems from the literature are reported and a comparison with five othermetaheuristic approaches for solving Vehicle Routing Problems is given.

    Notizen: Abstract In this paper we study the adaptive behavior of firms which repeatedly have to make a production decision. In a single good market the firms use own experience as well as information gathered by observing competitors to iteratively choose a production technology out of a given set. The adaptive learning of the firms is described in a dynamic model and analyzed in a simulation framework. We show that a small but positive propensity to imitate is optimal for the firms and yields production efficiencies above 95% of the maximal value. Furthermore, we observe that in a competitive situation firms using optimal propensities to imitate outmatch pure imitators and nonimitators in production efficiency as well as in profits.
