动态规划是对最优化问题的一种新的算法设计方法。由于各种问题的性质不同，确定最优解的条件也互不相同，因而动态规划的没计法对不同的问题，有各具特色的表示方式。-Dynamic programming optimization problem is a new method of algorithm design. The nature of the problem due to various different conditions to determine the optimal solution is also different from each other, which did not include dynamic programming method for different problems have different characteristics of the express way.
