Are COMPETants more competent for problem solving? The case of a multiple objective transportation problem

Hartl, Richard F.; Doerner, Karl; Reimann, Marc - 2001

In this paper we propose a multi-colony Ant System, where the colonies solve a multi-objective optimization problem concerned with goods transportation.

Insertion based Ants for Vehicle Routing Problems with Backhauls and Time Windows

Reimann, Marc; Doerner, Karl; Hartl, Richard F. - 2002

In this paper we present and analyze the application of an Ant System to the Vehicle Routing Problem with Backhauls and Time Windows (VRPBTW). At the core of the algorithm we use an Insertion procedure to construct solutions. We provide results on the learning and runtime behavior of the...
