WebNov 28, 2024 · A classic greedy case: interval scheduling problem. The heuristic is: always pick the interval with the earliest end time. Then you can get the maximal number of non-overlapping intervals. (or minimal number to remove). This is because, the interval with the earliest end time produces the maximal capacity to hold rest intervals.
