Breadth first search frontier
WebApr 12, 2016 · Breadth-first search (BFS) is an important graph search algorithm that is used to solve many problems including finding the shortest path in a graph and solving puzzle games (such as Rubik's Cubes). … 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 … See more Input: A graph G and a starting vertex root of G Output: Goal state.

In a stack, elements are added and removed from the top of the stack. Using a stack means that the path selected and removed from the frontier at any time is the last path that was added.
