Web1 Answer. The space complexity of the breadth-first search algorithm is O ( b d) in the worst case, and it corresponds to the largest possible number of nodes that may be stored in the frontier at once, where the frontier is the set of nodes (or states) that you are currently considering for expansion. WebMinimize estimated cost to reach a goal: Greedy search The simplest best-first strategy is to minimize the estimated cost to reach the goal, i.e., always expand the node that appears to be closest to the goal. ...
