Abstract

Graph signature is a fast isomorphism test that is used in self reconfiguration planning of modular robots. In case of dealing with homomorphic modules, the required time to calculate the signature grows exponentially with the number of symmetry lines. We tackle this problem by introducing an isomorphism- invariant signature calculation method, which is based on the power centrality of nodes. We also introduce a new sample-based search method. Simulation results show the new method finds better solutions in a significantly shorter time.
