Comparing the Optimization Behaviour of Heuristics with Topology Based Visualization

In this paper we propose some changes and extensions of the visualization approach that is used in the visualization tool dPSO-Vis. It is shown also how corresponding visualizations can help for the analysis of fitness landscapes of combinatorial optimization problems and for understanding and comparing the optimization behaviour of heuristics. As an example we use a small instance of the Travelling Salesperson Problem (TSP) and the three heuristics Greedy, Random greedy, and Simulated Annealing.
