WebBreadth-first search (BFS) is an algorithm for traversing or searching tree or graph data structures. It starts at the tree root (or some arbitrary node of a graph), and explores all … WebNov 8, 2024 · However, this space complexity is correct if you use a breadth-first search for the forward and backward searches (which is your scenario!), given that breadth-first …
WebSep 27, 2016 · Let be b the branching factor of the tree. Let be d the depth of the shallowest solution. Let be l the limit given to depth-limited search algorithm. Breadth-first search (BFS) In the worst case, suppose that our solution is at depth d, and we expand all nodes but the last node at level d, then the total number of generated nodes is $ O(b^{d}) $.
