Parallel breadth-first search
WebIs there a way to run BFS in parallel in Python? I'm just learning about parallel computing and I was wondering if there's a way to run breath first search in parallel, such that every node's neighbors will simultaneously be traversed. # BFS import collections def breadth_first_search (graph, root): visited, queue = set (), collections.deque ... 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.
