Performance analysis for multi-robot exploration strategies

Abstract

In this note, we compare four different exploration strategies and analyze the performance in terms of exploration time and amount of exploration per time step. In order to provide a suitable reference for comparison, we derive an upper bound for the theoretically achievable increase of explored area per time step. The comparison itself is done using a comprehensive empirical evaluation resulting in statistically significant performance differences. © 2010 Springer-Verlag Berlin Heidelberg.
