WebSolution: Yes. This is the same as the greedy ascent algorithm presented in Lecture 1. The algorithm will always eventually return a location, because the value of location that it stores strictly increases with each recursive call, and there are only a ﬁnite number of values in the grid. Hence, it will eventually return a value, which is always WebA greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach.
