Breadth first search with BackTracking. · GitHub

Breadth-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. Extra memory, usually a queue, is needed to keep track of the child nodes that were encountered but not yet explored. WebFeb 6, 2024 · Instead, backtracking occurs in the form of popping nodes off of the frontier. 2) The use of a stack for the frontier ensures that nodes are searched in a depth first ordering, since the most ... of gods and grunts
