Generalized Shortest Path Kernel on Graphs [PDF]

open access: yesarXiv, 2015
We consider the problem of classifying graphs using graph kernels. We define a new graph kernel, called the generalized shortest path kernel, based on the number and length of shortest paths between nodes. For our example classification problem, we consider the task of classifying random graphs from two well-known families, by the number of clusters ...

Shortest Path Analysis in Social Graphs [PDF]

open access: yesarXiv, 2014
The shortest path problem is among the most fundamental combinatorial optimization problems to answer reachability queries. It is hard to deter-mine which vertices or edges are visited during shortest path traversals. In this paper, we provide an empirical analysis on how traversal algorithms behave on social networks.

Shortest-Path Indices: Establishing a Methodology for Shortest-Path Problems

open access: yes, 2007
During the last years, impressive progress has been achieved in the field of algorithm engineering. A problem becoming more and more important is that of data dependency: the performance of an algorithm often highly depends on the input. Yet, for a given input, it is highly non-trivial to select the best solving strategy.

SOLVING QUICKEST PATH PROBLEM USING AN EXTENDED CONCEPT OF TRANSITIVE CLOSURE METHOD

open access: yesJurnal Informatika, 2005
A travel company offers a transportation service by picking up customers from certain places and sending them to the other places. Concerning traffic in time domain function for every path, the problem is how to find the quickest paths in picking up the ...

An Efficient Algorithm for Touring n Circles

open access: yesMATEC Web of Conferences, 2018
This paper proposed an intelligent algorithm, which can build the shortest path of the intersecting circle sequences in the plane. The problem is transformed to a corresponding problem of computing the shortest path of three disjoint circles.

On the Universal Near Shortest Simple Paths Problem [PDF]

open access: yesarXiv, 2019
This article generalizes the Near Shortest Paths Problem introduced by Byers and Waterman in 1984 using concepts of the Universal Shortest Path Problem established by Turner and Hamacher in 2011. The generalization covers a variety of shortest path problems by introducing a universal weight vector.

On the minimum eccentricity shortest path problem

open access: yesTheoretical Computer Science, 2015
Abstract In this paper, we introduce and investigate the Minimum Eccentricity Shortest Path (MESP) problem in unweighted graphs. It asks for a given graph to find a shortest path with minimum eccentricity. Let n and m denote the number of vertices and the number of edges of a given graph. We demonstrate that: • a minimum eccentricity shortest path

“rsppfp”: An R package for the shortest path problem with forbidden paths

open access: yesSoftwareX, 2019
The Shortest Path Problem with Forbidden Paths (SPPFP) is a variant of the original shortest path problem, where the constraints come from a set of forbidden arc sequences that cannot be part of any feasible solution.

Maximal buttonings of trees

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A buttoning of a tree that has vertices v1, v2, . . . , vn is a closed walk that starts at v1 and travels along the shortest path in the tree to v2, and then along the shortest path to v3, and so forth, finishing with the shortest path from vn to v1 ...
