Breadthfirst search  Definition In computer science, breadthfirst search (BFS) is a tree search algorithm used for traversing or searching a tree, tree structure, or graph.
In graph theory, breadthfirst search (BFS) is a graph search algorithm that begins at the root node and explores all the neighboring nodes.
Breadthfirst search, uniformcost search, and pure heuristic search are all special cases of a more general algorithm called bestfirst search.
BreadthFirst Search:  Remove a node from the queue. This becomes the current node.  Place all child nodes of the current node onto the queue. Newton's Method ...
Breadthfirst searches are expanded across before moving down (Matthews, 2000a). Figure 2, adapted from Matthews (2000a), illustrates the order that the nodes are explored. Figure 2  BreadthFirst Algorithm Node Expansion ...
In computer science, breadthfirst search (BFS) is a tree search algorithm used for traversing or searching a tree, graph. ... Depthfirst search (DFS) is an algorithm for traversing or searching a tree, tree structure, or graph. ...
Many algorithms textbooks describe graph searching algorithms that do not use heuristics (breadthfirst search, depthfirst search, Dijkstra's). Reading about them may help in understanding A*, which is a variant of Dijkstra's.

Since most browsers encourage depthfirst browsing, Letizia conducts a breadthfirst search concurrently for other useful locations that the user may be interested in.
search method that maintains a predetermined number of the best search paths found thus far at any given point. Thus, it considers more possibilities than depthfirst search, but avoids the exponential number of possibilities of breadthfirst search.
