A Class of Graph-Geodetic Distances Generalizing the Shortest-Path and the Resistance Distances
نویسنده
چکیده
A new family of distances for graph vertices is proposed. These distances reduce to the shortest path distance and to the resistance distance at the extreme values of the family parameter. The most important property of them is that they are graphgeodetic: d(i, j)+d(j, k) = d(i, k) if and only if every path from i to k passes through j. The construction of the distances is based on the matrix forest theorem and the graph bottleneck inequality.

A Family of Graph Distances Generalizing both the Shortest-Path and the Resistance Distances

متن کاملDevelopments in the theory of randomized shortest paths with a comparison of graph node distances
There have lately been several suggestions for parametrized distances on a graph that generalize the shortest path distance and the commute time or resistance distance. The need for developing such distances has risen from the observation that the above-mentioned common distances in many situations fail to take into account the global structure of the graph. In this article, we develop the theo...
متن کاملModeling of Optimal Distances of Surveying Stations for Monitoring Astable Engineering Structures Using Geodetic Methods
Large and astable engineering structures are the great importance and the behavior of such structures is usually made in Geotechnical and Geodetic methods (engineering geodesy). In the geodetic methods, the selection of appropriate surveying stations, in terms of distribution, locations, and distant of the target points to stations the control network, have a significant role in determining th...
متن کاملStudying New Classes of Graph Metrics
In data analysis, there is a strong demand for graph metrics that differ from the classical shortest path and resistance distances. Recently, several new classes of graph metrics have been proposed. This paper presents some of them featuring the cutpoint additive distances. These include the path distances, the reliability distance, the walk distances, and the logarithmic forest distances among...
متن کاملThe walk distances in graphs
The walk distances in graphs are defined as the result of appropriate transformations of the ∑∞ k=0(tA) k proximity measures, where A is the weighted adjacency matrix of a graph and t is a sufficiently small positive parameter. The walk distances are graphgeodetic; moreover, they converge to the shortest path distance and to the so-called long walk distance as the parameter t approaches its lim...
