WebDynamic Programming (commonly referred to as DP) is an algorithmic technique for solving a problem by recursively breaking it down into simpler subproblems and using the fact that the optimal solution to the overall problem depends upon the optimal solution to it’s individual subproblems. The technique was developed by Richard Bellman in the 1950s. WebSince all elements are nonnegative, the only way the submatrix sum equals 0 is if all elements are 0. The optimal solution for that problem is O (nm^2) or O (mn^2) 7 Reply …
