WebFeb 29, 2024 · Normally for Dijkstra there are two structures. The ordered list you have. A list of already processed nodes. You seem to be missing the second (I suppose it is stored as part of your graph model). do { current = queue.top (); queue.pop (); // You forgot to check if it has already been processed. // Ahhh. WebDijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph (single source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights. It has a time complexity of O (V^2) O(V 2) using the adjacency matrix representation of graph.
