The vague graphs are more flexible and compatible than fuzzy graphs due to the fact that they have many applications in networks. This paper presents an algorithm to find the shortest path in a directed graph whose arc length is taken as triangular vague number instead of real number. Finally...
The classical K Shortest Paths (KSP) problem, which identifies the k shortest paths in a directed graph, plays an important role in many application domains, such as providing alternative paths for vehicle routing services. However, the returned k shortest paths may be highly similar, i.e., ...
A. Introduction: The k shortest paths problem is a natural and long studied generalization of the shortest path problem, in which not only one but several paths in increasing order of length are sought. Given a directed graph G with nonnegative edge weights, a positive integer k, and two ...
In this work, we consider a well-known "Single Source Shortest Path Search" problems for weighted directed acyclic graphs (DAGs). We suggest a quantum algorithm with time complexity \(O(\sqrt {nm} \,\log \;n)\) and O (1/ n ) error probability, where n is a number of Vertexes, ...
We study the problem of finding a shortest path between two vertices in a directed graph. This is an important problem with many applications, including that of computing driving directions. We allow preprocessing the graph using a linear amount of extra space to store auxiliary information,...
TR = shortestpathtree(G,s) returns a directed graph, TR, that contains the tree of shortest paths from source node s to all other nodes in the graph. If the graph is weighted (that is, G.Edges contains a variable Weight), then those weights are used as the distances along the edges...

The Shortest Path algorithm is used to find the shortest path between two nodes in a graph.This algorithm applies to scenarios such as path design and network planning.Th
Plenty of algorithms rely on graphs. One of the most well-known algorithms on graphs isDijkstra’s algorithm , sometimes called the shortest path algorithm. As the name suggests, this simple yet effective algorithm finds the shortest path between two nodes in a graph. ...
