Greedy best first search time complexity
Greedy Best-First Search is an AI search algorithm that attempts to find the most promising path from a given starting point to a goal. The algorithm works by evaluating the cost of each possible path and then expanding the path with the lowest cost. WebWhat is time complexity of greedy best-first search algorithm?

Completeness: A search algorithm is complete when it returns a solution for any input if at least one solution exists for that particular input. Optimality: If the solution deduced by the algorithm is the best solution, i.e. it has the lowest path cost, then that solution is considered as the optimal solution.
