动态规划----矩阵连乘问题 动态规划法是解决问题的一种方法。它不规定为了得到结果需如何将问题划分为子问题的固定方法，而是按不同输入给出问题的具体实例的子问题划分方法，然后再进行运算、解答问题。 矩阵连乘问题的主要思想如下： 1）设置大小为连乘个数的方阵 2）主对角线上方各元素Di,j(i<j)表示矩阵Mi连乘到Mj的最小工作量 3）下方元素Di,j(i>j)记录获得该最小工作量矩阵分组的第一组的最后一个矩阵的序列号 最后通过下方元素可知最终结果的分组方式。-dynamic programming matrix continually multiply-dynamic programming problem is a problem-solving method. It does not require the results need to be how to divide the problems of the sub - problems fixed, but different input given by the specific example of the problem partition method, and then calculate, and answer questions. Matrix continually multiply the main idea is as follows : 1) the installation of the size of continually multiply the number phalanx 2) above the main diagonal elements Di, j (ilt; J) Matrix Mi continually multiply to the smallest workload 3) below elements Di, j (IGT; J) the record was the smallest workload of a matrix of the first group of a matrix of the final sequence, followed by the final element of the final results of the known clusters.
