Freemarker 简介 及手册
FreeMarker 手册 什么是FreeMarker? FreeMarker是一款模板引擎:即一种基于模板、用来生成输出文本(任何来自于HTML格式的文本用来自动生成源代码)的通用工具。它是为Java程序员提供的一个开发包,或者说是一个类库。它不是面向最终用户的,而是为程序员提供的一款可以嵌入他们所开发产品的应用程序。 FreeMarker实际上是被设计用来生成HTML页面,尤其是通过

首先不得不感叹一句学科的交叉性,上个星期刚刚从vrp问题中了解到单纯形法和罚函数,最近就在数学建模的书上看到规划问题的<em>求解</em>(早点看到就好啦....)    规划问题分为线性规划问题和非线性规划问题,线性规划问题目前用单纯形法可以很好的解决,而非线性规划问题则没有很好的解法,根据实际问题具体分析(从编程的角度我采用过动态规划,搜索,分支限定法,以及计算智能中的相关算法)。   什么是线性规划问题
