Dijkstra algorithm in data structure javatpoint

WebSep 28, 2024 · Dijkstra's Algorithm basically starts at the node that you choose (the source node) and it analyzes the graph to find the shortest path between that node and all the other nodes in the graph. The algorithm keeps track of the currently known shortest distance from each node to the source node and it updates these values if it finds a shorter path. WebIn this article, we have explored the Time & Space Complexity of Dijkstra's Algorithm including 3 different variants like naive implementation, Binary Heap + Priority Queue …

WebDijkstra’s algorithm solves the single-source shortest-paths problem on a directed weighted graph G = (V, E), where all the edges are non-negative (i.e., w (u, v) ≥ 0 for each edge (u, v) Є E ). In the following algorithm, we will use one function Extract-Min (), which extracts the node with the smallest key.
