WitrynaDijkstra 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. ionia county dog pound https://mjmcommunications.ca
