Algorithm Step 1 : Create a set shortPath to store vertices that come in the way of the shortest path tree. Step 2 : Initialize all distance values as INFINITE and assign distance values as 0 for source vertex so that it is picked first. Step 3 : Loop until all vertices of the graph...

A 'Shortest Path Algorithm' refers to a computational method used in computer science to find the most efficient route between two points in a network, such as an IP network or a telephone network. It is particularly useful for applications like routing in IP networks and dynamic call routing...

Shortest path problem is of most important in the networks and of most interest to study. For example we can consider we want to send packet from one node to another to achieve throughput we required to follow the shortest path available between two nodesPI Patil...

In this paper, we report on our own experience in studying a fundamental problem on graphs: all pairs shortest paths. In particu- lar, we discuss the interplay between theory and practice in engineering a simple variant of Dijkstra's shortest path algorithm. In this context, we show that ...
Shortest path between two single nodes collapse all in pageSyntax P = shortestpath(G,s,t) P = shortestpath(G,s,t,'Method',algorithm) [P,d] = shortestpath(___) [P,d,edgepath] = shortestpath(___)Description P = shortestpath(G,s,t) computes the shortest path starting at source ...
This sum of weights along the edges that make up a path is called a path cost or a path weight.Algorithms that find the shortest paths, like Dijkstra's algorithm or the Bellman-Ford algorithm, find the shortest paths from one start vertex to all other vertices....
