Metric Embedding via Shortest Path Decompositions

open access: yes, 2019
We study the problem of embedding shortest-path metrics of weighted graphs into $\ell_p$ spaces. We introduce a new embedding technique based on low-depth decompositions of a graph via shortest paths.

A New Algorithm for the Discrete Shortest Path Problem in a Network Based on Ideal Fuzzy Sets [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2013
A shortest path problem is a practical issue in networks for real-world situations. This paper addresses the fuzzy shortest path (FSP) problem to obtain the best fuzzy path among fuzzy paths sets. For this purpose, a new efficient algorithm is introduced

Structural factoring approach for analyzing stochastic networks [PDF]

open access: yes
The problem of finding the distribution of the shortest path length through a stochastic network is investigated. A general algorithm for determining the exact distribution of the shortest path length is developed based on the concept of conditional ...

Constrained shortest paths and related problems

open access: yes, 2001
The classical shortest path problem, to find a path of minimal cost between two nodes in a graph, is efficiently solvable in polynomial time. However, in many applications we also have additional budget or resource constraints on a path. This problem is known as constrained shortest path problem and unfortunately belongs to the class of "hard" problems

Solving the robust shortest path problem with interval data using a probabilistic metaheuristic approach

open access: yes, 2016
This paper addresses the robust shortest path problem with interval data, i.e. the case of classical shortest path problem with given source and sink when arc weights are not fixed but take their values from some intervals associated with arcs.
