WebA Greedy algorithm makes greedy choices at each step to ensure that the objective function is optimized. The Greedy algorithm has only one shot to compute the optimal solution so that it never goes back and reverses the decision. Greedy algorithms have some advantages and disadvantages: WebJan 23, 2024 · 1. The Greedy algorithm follows the path B -> C -> D -> H -> G which has the cost of 18, and the heuristic algorithm follows the path B -> E -> F -> H -> G which has the cost 25.
