Zusammenfassung: | Abstract: "Coherent algebras are a very promising tool to get more insight into the graph isomorphism problem. This paper deals with the aspect of computing the coherent algebra which is generated by some matrices A, ..., A[subscript m] of dimension n x n. It is proved that the well known Weisfeiler-Lehman algorithm can be implemented to run in time O((m+n)n²log n). Using a graphtheoretic formulation of the properties of coherent algebras we present an improved version of this algorithm. We further point out a relationship of coherent algebras and total degree partitions which also play an important role for the graph isomorphism problem." |
