Introduction to Greedy Method and its Applications

Greedy algorithms produce good solutions on some mathematical problems, but not on others. Most problems for which they work will have two properties: Greedy choice property We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far, but not on future choic… WebJul 4, 2024 · Divide and conquer: Does more work on the sub-problems and hence has more time consumption.
