WebJan 28, 2024 · This type of BFS is used to find shortest distance or path from a source node to a destination node in a graph with edge values 0 or 1. When the weights of edges are 0 or 1, the normal BFS techniques provide erroneous results because in normal BFS technique, its assumed that the weight of edges would be equal in the graph. WebBFS and shortest path help needed. So basically; I have this working. I have an adjacency list that represents a 3 x 3 grid and a shortestPath () function that takes two arguments, start and end. When invoked it returns all the correct data. However; I need to refactor it so that the grid uses coordinates instead of values.

Store each cell as a node with their row, column values and distance from source cell. Start BFS with source cell. Make a visited array with all having “false” values except ‘0’cells which are assigned “true” values as they can not be traversed.

WebBFS and DFS work on both directed and undirected graphs, as shown in the figures above. If the underlying graph is disconnected, BFS and DFS can only traverse the connected component that the given starting node belongs to. BFS cannot be used to find shortest paths on weighted graphs. See Dijkstra’s algorithm for that!
