Graph-theoretic distance
WebSep 20, 2011 · Not all applications of graph-theoretic connectivity apply critical distances; several studies have used pair-wise ‘probability of connectivity’ matrixes that can be constructed either via the use of a declining-by-distance dispersal kernel or via more complicated path-type calculations (Urban & Keitt 2001; Saura & Pascual-Hortal 2007). WebOct 1, 2006 · The length of a geodesic path between two nodes is known as the geodesic or graph-theoretic distance between them. We can represent the graph theoretic distances between all pairs of nodes as a matrix D in which d ij gives the length of the shortest path from node i to node j. 3. Comparison of methods

A pair of connected distance-regular graphs are cospectral if and only if they have the same intersection array. WebGraph-Theoretic Methods, 3 of 23 The degree of a vertex is the number of vertices that it connects with. In the case of a directed graph, one needs to distinguish between the outgoing degree and the incoming degree. The distance between two vertices is the minimum number of edges that must be traversed to pass between them.
In the mathematical field of graph theory, the distance between two vertices in a graph is the number of edges in a shortest path (also called a graph geodesic) connecting them. This is also known as the geodesic distance or shortest-path distance. Notice that there may be more than one shortest path … See more A metric space defined over a set of points in terms of distances in a graph defined over the set is called a graph metric.
