Memoized matrix chain

WebThe matrix-chain multiplication problem can be solved by either a bottom-up dynamic programming algorithm or a top-down, memoized dynamic-programming algorithm. The running time of both algorithms is Θ (n 3 ), and the algorithm needs Θ (n 2) space. http://lak.informatik.uni-freiburg.de/lak_teaching/ws07_08/algotheo/Slides/14_2_DP_matrix_chains.pdf
