WebOct 15, 2024 · The Epsilon-Greedy Algorithm (ε-Greedy) As we’ve seen, a pure Greedy strategy has a very high risk of selecting a sub-optimal socket and then sticking with this selection. As a result, the best socket will never be found. A simple way to overcome this problem is by introducing an element of exploration. This is exactly what Epsilon-Greedy … A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage.
