中文说明：资源描述1 非线性规划 1.1 非线性规划的实例与定义 如果目标函数或约束条件中包含非线性函数，就称这种规划问题为非线性规划问 题。一般说来，解非线性规划要比解线性规划问题困难得多。而且，也不象线性规划有 单纯形法这一通用方法，非线性规划目前还没有适于各种问题的一般算法，各个方法都 有自己特定的适用范围。 下面通过实例归纳出非线性规划数学模型的一般形式，介绍有关非线性规划的基本 概念。 例 1 （投资决策问题）某企业有n 个项目可供选择投资，并且至少要对其中一个 项目投资。已知该企业拥有总资金 A元，投资于第i(i = 1,L,n)个项目需花资金 i a 元， 并预计可收益i b 元。试选择最佳投资方案。
English Description：
Application background1 nonlinear programming1.1 examples and definitions of nonlinear programmingIf the objective function or constraint condition contains a nonlinear function, it is called a nonlinear programming problem.Questions. Generally speaking, the problem of solving nonlinear programming is more difficult than solving linear programming problems. Moreover, it is not linear programming.The simplex method is a general method, which is not suitable for all kinds of problems.Have their own specific scope of application.The general form of nonlinear programming mathematical model is summarized in this paper.Concept.Example 1 (investment decision problem) a company has a n project to choose to invest, and at least one of themProject investment. Known that the company has a total capital of A yuan, investment in I (I = 1, L, n) a project to spend money a i,And is expected to return B I yuan. Try to choose the best investment plan.
