WebMay 20, 2024 · The time complexity of Dijkstra's algorithm is O(V^2), where V is the number of vertices in the graph. However, if the input graph is represented using an adjacency list (method of representation of graph), then the time complexity can be reduced to O(E log V) using a binary heap. WebThe Dijkstra Shortest Path algorithm computes the shortest path between nodes. The algorithm supports weighted graphs with positive relationship weights. The Dijkstra Single-Source algorithm computes the shortest paths between a source node and all nodes reachable from that node.
