This procedure involves simplifying a graph isomorphism problem by either identifying smaller “Johnson” graphs within the two graphs being compared, or finding a way to color the two graphs that ...

Weisfeiler-Leman Graph Isomorphism This crate provides a implementation of the Weisfeiler-Leman (WL) graph isomorphism algorithm for petgraph graphs. WL is a sound but incomplete isomorphism test, ...

The graph isomorphism problem simply asks whether two graphs are the same, regardless of how they are drawn or how their nodes are named.

Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a public transportation network. Mathematicians have long sought to develop ...

When running the program, first enter the number of graphs in the series, and then enter the shared (partial) name xxx, for example, the total number of non-isomorphic graphs with five vertices is 21, ...

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 ...

Querying large graphs to retrieve information in permissible time is an emerging research problem, and it has roots in various application domains, mainly to analyse large networks. For a given query ...
