The breadth-first-search algorithm is a way to explore the vertices of a graph layer by layer. It is a basic algorithm in graph theory which can be used as a part of other graph algorithms. For instance, BFS is used by Dinic's algorithm to find maximum flow in a graph.
Best-first search is a class of search algorithms which explores a graph by expanding the most promising node chosen according to a specified rule.. Judea Pearl described best-first search as estimating the promise of node n by a "heuristic evaluation function () which, in general, may depend on the description of n, the description of the goal, the information gathered by the search up to ...
The wavefront expansion algorithm is a specialized potential field path planner with breadth-first search to avoid local minima. [ 1 ] [ 2 ] It uses a growing circle around the robot. The nearest neighbors are analyzed first and then the radius of the circle is extended to distant regions.
If G is a tree, replacing the queue of this breadth-first search algorithm with a stack will yield a depth-first search algorithm. For general graphs, replacing the stack of the iterative depth-first search implementation with a queue would also produce a breadth-first search algorithm, although a somewhat nonstandard one. [10]
You can use cheese as a treat substitute or to disguise your pet's pills. Depending on the type, cheese isn't inherently unhealthy for dogs. But that doesn't mean it should be eaten with every meal.

We should either have only a pseudocode implementation, or maybe Python or some other reads-mostly-like-pseudocode language if it can be made sufficiently close to pseudocode. The fact that java.util.LinkedList is in the example suggests to me that the example says more about Java than about BFS. —Ben FrantzDale 12:53, 11 May 2010 (UTC)
