一、知识概述方案优化设计,一般是通过问题的情景,给出若干信息,提出解决问题的要求,让学生应用数学的知识和技能,进行分析、设计或操作,寻求最佳解决方法(最大利润、最小投入、最大值、最小值等最值问题).方案优化设计,即属于方法开放性问题,又利于考查学生的阅读理解能力、分析推理能力、数据处理能力、文字概括能力、书面表达能力和动手实践能力,所以是近年中考的热点题型.二、主要类型方案优化(指最远,最近,最大利润,最小投资,最 First, an overview of knowledge Optimization program design, the general situation is through the problem, given a number of information, put forward the requirements to solve the problem, so that students apply mathematical knowledge and skills, analysis, design or operation, to find the best solution (maximum profit , Minimum input, maximum, minimum and so on.) Optimization of program design, that is, the method of open issues, but also conducive to examine students' reading comprehension, analytical reasoning ability, data processing capabilities, text summarizing ability, writing ability And hands-on practical ability, it is the hottest type of exam in recent years. Second, the main types of program optimization (referring to the farthest, recently, the maximum profit, the minimum investment, the most
