This example is an introduction to pygmtools which shows how to match isomorphic graphs. Isomorphic graphs mean graphs whose structures are identical, but the node correspondence is unknown. # Author: ...

We investigate the interplay between the graph isomorphism problem, logical definability, and structural graph theory on a rich family of dense graph classes: graph classes of bounded rank width. We ...

Given two graphs which are almost isomorphic, is it possible to find a bijection which preserves most of the edges between the two? This is the algorithmic task of Robust Graph Isomorphism, which is a ...

Calculation and isomorphism is one of the important topics in graph theory. Especially to keep some structure parameters of graph invariant operation is the focus of attention of the structure graph.

We show that the groupoids of two directed graphs are isomorphic if and only if the two graphs are orbit equivalent by an orbit equivalence that preserves isolated eventually periodic points. We also ...

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 ...

We prove that for friendly graphs, the convex relaxation is guaranteed to find the exact isomorphism or certify its inexistence. This result is further extended to approximately isomorphic graphs, for ...
