动态规划解决0-1背包问题-0-1 knapsack problem

加强肋 理想的设计 为了克服壁厚大可能引起的问题，使用是一种可减少壁厚并能增加刚性的有效方法。 一般来说，部件的刚性可用以下方法增强 增加壁厚； 增大弹性模量（如加大增强纤维的含量）； 设计中考虑。 如果设计用的材料不能满足所需刚性，则应选择具有更大弹性模量的材料。简单的方法是增加塑料中增强纤维的含量。但是，在特定壁厚下，这种方法仅能使刚性呈线性增长。更有效的方法是使用经过优化设计的。由于惯性力矩增大，部件的刚性便会增大。在优化的尺寸时，不但要考虑工程设计应当考虑的问题，还应考虑与生产和外观有关的技术问题。 优化的尺寸 大的惯性力矩可很容易地通过设置又厚又高的来实现。但是对热塑性工程塑料，这种方法常会产生制品表面凹痕、内部空洞和翘曲等问题。而且，如果的高度过高，在负荷下结构将有可能膨胀。出于这种考虑，必须在合理比例内保持的尺寸（见图1）。-stiffened ideal for the design of large thickness overcome the problems that may arise. use of a reduced wall thickness and rigidity can increase the effective method. In general, the rigid parts of the following methods can be used to enhance increased thickness; increased elastic modulus (such as increasing fiber content); Design considerations. If the design of the materials used can not meet the rigid requirements, they should have a greater choice of elastic modulus of the material. The simple way out is to increase plastics reinforced fiber content. However, in s
