Breadth First Search or BFS for a Graph

WebNov 2, 2016 · Consider the basic non-recursive DFS algorithm on a graph G=(V,E) (python-like pseudocode below) that uses array-based adjacency lists, a couple of arrays of size V, and a dynamic array stack of size <= V. If I understand correctly, this is a cache oblivious algorithm since no information about the memory configuration is provided. WebBreadth-first search ( BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.
