Dynamic programming vs greedy algorithms
WebApr 2, 2024 · Dynamic Programming Approach. Dynamic programming is a popular algorithmic paradigm, and it uses a recurrent formula to find the solution. It is similar to the divide and conquer strategy since it breaks down the problem into smaller sub-problems. The major difference is that in dynamic programming, sub-problems are interdependent. WebNov 4, 2024 · Dynamic programming requires more memory as it stores the solution of each and every possible sub problems in the table. It does lot of work compared to …
