Breadth search algorithm python
WebBreadth-first search assigns two values to each vertex v v v v: A distance , giving the minimum number of edges in any path from the source vertex to vertex v v v v . The … WebBreadth-first search (BFS) is an algorithm used for tree traversal on graphs or tree data structures. BFS can be easily implemented using recursion and data structures like dictionaries and lists. ... An easy way to do this in Python is to use a dictionary data structure, where each vertex has a stored list of its adjacent nodes. Line 12: ...
