Given an unweighted, undirected graph of V nodes and E edges, a source node S, and a destination node D, we need to find the shortestpath from node S to node D in the graph.
The usual way to calculate a shortestpath is to start like you do, but make a note whenever you encounter a new node and record the previous node on the path. Then, when you reach the target node, you can follow the backlinks to the source and get the path.

Welcome to this comprehensive tutorial on the UnweightedShortestPath algorithm in Graph Theory! 📈 In this video, we'll break down each concept step-by-step, using clear diagrams to help...
In this tutorial, we will discuss how to find the shortestpath in an unweightedgraph. In an unweightedgraph, no edges have weight or all edges have the same weight.
I'd like to find all shortestpath in an unweightedgraph. In my first attempt I managed to find only one shortpath using BFS. I used a stack to save the shortestpath and a queue for BFS. The vi...
ShortestPaths # The shortest path problem involves finding a path between two nodes in a graph such that the total distance is minimized. In unweightedgraphs this means finding the path with the fewest number of edges. In weighted graphs it is the path with minimum sum of weights associated to the path edges. This problem definition applies for both undirected and directed graphs. In ...
In the next sections, first we’ll examine the code to find the shortest distance between a specified start and end node. Next, we’ll enhance this algorithm to determine the shortest distances from the start node to all other nodes in the graph.
