WebDijkstra algorithm is one of the prominent algorithms to find the shortest path from the source node to a destination node. It uses the greedy approach to find the shortest path. The concept of the Dijkstra algorithm is to find the shortest distance (path) starting from the source point and to ignore the longer distances while doing an update. WebJun 20, 2024 · A Refresher on Dijkstra’s Algorithm. Dijkstra’s Algorithm is one of the more popular basic graph theory algorithms. It is used to find the shortest path between nodes on a directed graph. We start with a source node and known edge lengths between nodes. We first assign a distance-from-source value to all the nodes.
