Dijkstra’s Algorithm for Adjacency List Representation

WebIn this article, we will see the implementation of the Dijkstra algorithm using the priority queue of C++ STL. Dijkstra algorithm is used to find the shortest path from the source to the destination in an undirected graph. Let us consider a source vertex 0, we have to find the shortest path from the source vertex to all the vertices in the graph. WebSep 28, 2024 · With Dijkstra's Algorithm, you can find the shortest path between nodes in a graph. Particularly, you can find the shortest path from a node (called the "source node") to all other nodes in the graph, producing a shortest-path tree. This algorithm is used in GPS devices to find the shortest path between the current location and the destination. laura and lawrence nelson

WebJun 8, 2024 · Algorithm. Here is an algorithm described by the Dutch computer scientist Edsger W. Dijkstra in 1959. Let's create an array d [] where for each vertex v we store the current length of the shortest path from s to v in d [ v] . Initially d [ s] = 0 , and for all other vertices this length equals infinity. WebFeb 27, 2024 · This project involves implementing an adjacency list representation of a weighted graph, and using it to apply Dijkstra’s shortest paths algorithm (single-source, all destinations – SSAD) to a weighted directed graph.

WebDijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph (single source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights. It has a time complexity of O (V^2) O(V 2) using the adjacency matrix representation of graph.
