WebMay 11, 2024 · Greedy Best First Search, on the other hand, uses less memory, but does not provide the optimality and completeness guarantees of A*. So, which algorithm is the "best" depends on the context, but both are "best"-first searches. Note: in practice, you may not use any of these algorithms: you may e.g. use, instead, IDA*. WebAug 4, 2024 · Informed algorithms utilise the information in the problem statement to solve the problem more optimally in terms of computing cost or time, similar to Greedy Best First Search (GBFS) and A* algorithm.
