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 ...
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 the 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 ...
Parallel breadth-first search. 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.
Depth-first search ( DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the ...

Graph traversal. In computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified by the order in which the vertices are visited. Tree traversal is a special case of graph traversal.
Beatles for Sale is the fourth studio album by the English rock band the Beatles.It was released on 4 December 1964 in the United Kingdom on EMI's Parlophone label. The album marked a departure from the upbeat tone that had characterised the Beatles' previous work, partly due to the band's exhaustion after a series of tours that had established them as a worldwide phenomenon in 1964.
