The above isomorphism has been established in several places in the literature (see for … WebApr 25, 2024 · Isomorphic graphs mean that they have the same structure: identical connections but a permutation of nodes. The WL test is able to tell if two graphs are non-isomorphic, but it cannot guarantee that they are isomorphic. Two isomorphic graphs. This might not seem like much, but it can be extremely difficult to tell two large graphs apart.
