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]. Webof a graph is the minimum eccentricity of any vertex. • The diameter of a graph is the …

WebAlgebraic graph theory is a branch of mathematics in which algebraic methods are applied to problems about graphs. This is in contrast to geometric, combinatoric, or algorithmic approaches. There are three main branches of algebraic graph theory, involving the use of linear algebra, the use of group theory, and the study of graph invariants .

WebMar 17, 2024 · The graph whose vertices correspond to the points in the plane with integer coordinates, -coordinates in the range and -coordinates in the range and two vertices are connected by an edge whenever the corresponding points are at distance 1, is a common form of lattice graph. In other words, for the point set mentioned, it is a unit distance graph.
