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. WebInterval Scheduling Interval Partitioning Scheduling to Minimize Lateness What is a Greedy Algorithm? No real consensus on a universal de nition. Greedy algorithms: make decision incrementally in small steps without backtracking decision at each step is based on improving local or current state in a myopic fashion without paying attention to the
