WebFeb 9, 2008 · The underlying idea of dynamic programming is: avoid calculating the same stuff twice, usually by keeping a table of known results of subproblems. Unlike divide-and-conquer, which solves the subproblems top-down, a dynamic programming is a bottom-up technique. Bottom-up means Start with the smallest subproblems.
