Implementing dijkstra's algorithm in python

Witryna19 lut 2024 · Dijkstra’s shortest path algorithm. This algorithm is used to calculate and find the shortest path between nodes using the weights given in a graph. (In a network, the weights are given by link-state packets and contain information such as the health of the routers, traffic costs, etc.). Summary of the working WitrynaBasic algorithm. From each of the unvisited vertices, choose the vertex with the smallest distance and visit it. Update the distance for each neighboring vertex, of the visited vertex, whose current distance is greater than its sum and the weight of the edge between them. Repeat steps 1 and 2 until all the vertices are visited.
