WebJun 7, 2024 · 2. I have coded a greedy recursive algorithm to Find minimum number of coins that make a given change. Now I need to estimate its time complexity. As the algorithm has nested "ifs" depending on the same i (n * n), with the inner block halving the recursive call (log (2)n), I believe the correct answer could be O (n*log (n)), resulting from … WebThe worst-case complexity for greedy search is O(b m), where m is the maximum depth of the search. Its space complexity is the same as its time complexity, but the worst case can be substantially reduced with a good heuristic function. ...

WebJul 30, 2024 · The time complexity for the standard greedy algorithm is O(n*log(n)), if step 3 does not take longer. In this case, the internet says that the time complexity is O(n^2*log(n)), because the algorithm has to check if there is a cycle before adding any edge to the list and I don't know how to demonstrate this complexity. A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time.
