Beam search: is a heuristic search algorithm that is an optimization of best-first search that reduces its memory requirement. Beam stack search: integrates backtracking with beam search. Best-first search: traverses a graph in the order of likely importance using a priority queue. Bidirectional search: find the shortest path from an initial vertex to a goal vertex in a directed graph. Bloom filter: a constant time and memory check to see whether a given element exists in a set.
