WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem. WebJul 4, 2024 · Divide and conquer: Does more work on the sub-problems and hence has more time consumption. In divide and conquer the sub-problems are independent of each other. Dynamic programming: Solves the sub-problems only once and then stores it in the table. In dynamic programming the sub-problem are not independent.
