(algorithm)
Definition: Any search algorithm that considers neighbors of a vertex, that is, outgoing edges of the vertex's predecessor in the search, before any outgoing edges of the vertex. Extremes are searched last. This is typically implemented with a queue.
See also depth-first search, best-first search.
Note: In a tree, called a level-order traversal.
