الوصف: A commonly studied means of parameterizing graph problems is the deletion distance from triviality [11], which counts vertices that need to be deleted from a graph to place it in some class for which e cient algorithms are known. In the context of graph isomorphism, we de ne triviality to mean a graph with maximum degree bounded by a constant, as such graph classes admit polynomial-time isomorphism tests. We generalise deletion distance to a measure we call elimination distance to triviality, based on elimination trees or tree-depth decompositions. We establish that graph canonisation, and thus graph isomorphism, is FPT when parameterized by elimination distance to bounded degree, extending results of Bouland et al. ; The work was supported in part by EPSRC grant EP/H026835, DAAD grant A/13/05456, and DFG project Logik, Struktur und das Graphenisomorphieproblem. ; This is the final version of the article.
