Dijkstra's algorithm (/ ˈdaɪk.strəz /, DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, a road network.

Jan 21, 2026 · Dijkstra’s algorithm always picks the node with the minimum distance first. By doing so, it ensures that the node has already checked the shortest distance to all its neighbors.

Developed by computer scientist Edsger W. Dijkstra in 1956 and published in 1959, Dijkstra’s algorithm has become a foundational concept in computer science and graph theory. In this tutorial, we’ll …

Dijkstra's algorithm is used for solving single-source shortest path problems for directed or undirected paths. Single-source means that one vertex is chosen to be the start, and the algorithm will find the …

A graph visualization tool that can simulate Dijkstra's shortest path algorithm.

For a given source node in the graph, the Dijkstra algorithm finds the shortest path between that node and every other. The idea is to traverse the graph in a way that visited nodes can not be reached …
