In this article, we considered the isomorphism and canonization problem for graphs of bounded rank width. The first main result is that the Weisfeiler-Leman dimension of graphs of rank width at most k ...

We show that graph isomorphism is in the complexity class SPP and hence it is in /spl oplus/P (in fact, it is in Mod/sub k/P for each k/spl ges/2). We derive this result as a corollary of a more ...

Attributed graphs are widely used in many application domains, for example to model social networks. An attributed graph is a graph in which vertices and edges may have types and other attributes.

Checking isomorphism of graphs with python This project has been created for Discrete Mathematics 1 and is meant to check isomorphism of two simple, non-directional graphs. Graphs can be entered ...

The graph isomorphism problem remains one of those mysteries in theoretical computer science that fascinates laypersons and experts alike. In 1979, Garey and Johnson mentioned the problem in their ...

Graph-Isomorphism-ACO This project addresses the Graph Isomorphism Problem, which involves determining whether two graphs are structurally identical (isomorphic). The project implements three ...

The graph isomorphism problem has been labeled as NP, though some have suggested it should be NP complete—it involves trying to create an algorithm able to look at two networks (with nodes and ...

The difficulty of some mathematical problems lies in not knowing how hard they are. This is the case with an important problem in computer science called "graph isomorphism testing" whereby ...
