Each basis determines a unique BFS: for each basis B of m indices, there is at most one BFS with basis B. This is because x B {\displaystyle \mathbf {x_{B}} } must satisfy the constraint A B x B = b {\displaystyle A_{B}\mathbf {x_{B}} =b} , and by definition of basis the matrix A B {\displaystyle A_{B}} is non-singular, so the constraint has a ...
Animated example of a breadth-first search. Black: explored, grey: queued to be explored later on BFS on Maze-solving algorithm Top part of Tic-tac-toe game tree Breadth-first search ( BFS ) is an algorithm for searching a tree data structure for a node that satisfies a given property.
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.
The algorithm is called lexicographic breadth-first search because the order it produces is an ordering that could also have been produced by a breadth-first search, and because if the ordering is used to index the rows and columns of an adjacency matrix of a graph then the algorithm sorts the rows and columns into lexicographical order.

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 ...
