Webb31 okt. 2024 · Conclusion Greedy algorithms are usually easy to think of, easy to implement and run fast. Proving their correctness may require rigorous mathematical … Webb15 apr. 2024 · With the given policy function, we choose a certain action at a state in a greedy way. In other words, when the policy function is unknown, we rely on the reward function to solve the optimal policy. When a specific policy is found, a greedy search algorithm can be employed to select the best action, and the resulting state-action …

Greedy algorithms usually involve a sequence of choices. The basic proof strategy is that we're going to try to prove that the algorithm never makes a bad choice. Greedy algorithms can't backtrack -- once they make a choice, they're committed and will never undo that choice -- so it's critical that they never make a bad … Visa mer As a first step, I recommend you use random testing to test your algorithm.
