协同过滤算法
这是用于商品推荐的协同过滤算法。本算法的相似性度量采用的是皮尔森相似性。代码采用基于iterm的协同过滤,即先建立iterm的临近矩阵,对未打分的term采用临近矩阵进行打分。

Have you ever wanted to copy a file from your Desktop Computer to your handheld Pocket PC? This included any Windows CE version too? Well if so, I will present an easy way to do it here: It s called the Remote Application Programming Interface, or, RAPI in this article. It is touched on in the MSDN but not really explained very well.

//就是一个封闭区域,要用不同的颜色填充,先在其内部选中一点象素作为“种子”,对其填充,然后判//断其上下左右的象素是否在封闭区域内且未被填充,如果是则也把它选为“种子”压入栈,再从栈中弹//出一个对其填充,再判断其上下左右的象素,如此往复,直到最后一个象素被填充为止。
//说明程序用递归 来实现
//fill_point(x,y) //把x,y 单元格进行填充
//is_inner(x,y) 判断x,y是否是单元格内部的点,如果是则返回1否则0-Seed filling algorithm
