WebFeb 23, 2024 · A Greedy algorithm is an approach to solving a problem that selects the most appropriate option based on the current situation. This algorithm ignores the fact that the current best result may not bring about the overall optimal result. Even if the initial decision was incorrect, the algorithm never reverses it. WebApr 28, 2024 · This approach makes the decision tree a greedy algorithm — it greedily searches for an optimum split at the root node and repeats …
