WebJan 22, 2014 · Any graph gives rise to an \mathbb {N} -enriched category, the objects being the vertices and the homs being distances in the graph. So, we get an invariant of graphs — and that’s what’s called magnitude. WebJan 1, 2024 · Formally, those properties are called invariants; to define them, we first …

The difference between several metric dimension graph invariants

WebIn the context of graph isomorphism testing, so-called complete graph invariants have been investigated [9,11]. Such a graph invariant has the property that it discriminates all non-isomorphic graphs uniquely (i.e., without any degeneracy) and isomorphic graphs are mapped to equal values [9,11]. http://courses.ics.hawaii.edu/ReviewICS241/morea/graphs/Graphs3-QA.pdf green people founded

WebJun 6, 2024 · Graph invariants provide an amazing and may be the single expository tool for investigation of abstract structures of graphs. They contain global and general information about a graph and its particular substructures such as cycle structures, matchings, colorings, factors, and coverings. WebThere are many examples of graph parameters, specially based on distances which are applicable in chemistry. The Wiener index is probably the most studied graph invariant in both theoretical and practical meanings (cf. [4,6–11,22]). Apart from the Wiener index, we will consider some other related indices.
