Resumo
This work treats the application of the eigenvector centrality in solving the Graph Isomorphism Problem. This property, taken from spectral graph theory, was used by Philippe Santos in [SANTOS 2010] to propose a spectral algorithm for solving this problem. An adaptation of the power method is proposed to compute the eigenvector centrality, producing a competitive version to the spectral algorithm of [SANTOS 2010]. Based on this adaptation, the efficiency of the eigenvector centrality in solving the problem is studied. In addition, it is proposed an iterative labeling algorithm, called Centrality Based Iterative Algorithm, which can be applied to any type of graph, including regular ones. Several tests are performed to compare the two proposed algorithms with some others well-known algorithms from literature, such as Nauty.
