The … 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. Webgreedy strategy is at most O(lnjHbj) times that of any other strategy. We also give a bound for arbitrary ˇ, and show corresponding lower bounds in both the uniform and non-uniform cases. Variants of this greedy scheme underlie many active learning heuristics, and are often de-scribed as optimal in the literature. fnb spearville online banking
