WebFeb 27, 2024 · Dijkstra's Algorithm on Digraph in C++ Feb 27, 2024 Introduction 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’s Algorithm allows you to calculate the shortest path between one node and every other node in a graph. Algorithm Execution Here’s how the algorithm is implemented: Mark all nodes as unvisited. Mark the initially selected node with the current distance of 0 0 and the rest with infinity. Set the initial node as the current node.
