一. 爬山算法 ( Hill Climbing )爬山算法是一种简单的贪心搜索算法，该算法每次从当前解的临近解空间中选择一个最优解作为当前解，直到达到一个局部最优解。爬山算法实现很简单，其主要缺点是会陷入局部最优解，而不一定能搜索到全局最优解。假设C点为当前解，爬山算法搜索到A点这个局部最优解就会停止搜索，...

之前 写过一篇在 ubuntu 下安装 TensorFlow 的教程，那个时候 TensorFlow 官方还不支持 Windows 系统，虽然可以通过其他方法安装，但是终究不是原生的，而且安装过程繁琐易错。好消息是，Google官方在11月29号的开发者博客中宣布新的版本（0.12）将 增加对Windows的支持，我11月30号知道的，立马就安装试了试，安装过程非常简单，不过也有一些需要手动调整。

今天来说一下机器学习库 TensorFlow 的在 Ubuntu14.04 64位下的安装。更新这里我会列出对本文的更新。2017 年 10 月 13 日： 优化排版，与其他博文保持统一。去掉公众号相关内容。什么是 TensorFlow关于什么是 TensorFlow ，这里引用一下 官网 的介绍： TensorFlow™ is an
