The Knapsack Problem Everyday Dynamic Programming Overlapping Subproblems A problem is said to have overlapping subproblems if it can be broken down into subproblems which are reused multiple times. This is closely related to recursion. To see the difference consider thefactorialfunction, defined as fo...

Dynamic Programming Compare to Greedy and Divide_and_conquer Greedy.Build up a solution incrementally, myopically optimizing some local criterion. Divide-and-conquer.Break up a problem into sub-problem into sub-problems, solve each sub-problem independently, and combine solutions to sub-problems to ...
