The equation Problem Description There is an equation ax + by + c = 0....Given a,b,c,x1,x2,y1,y2 you must determine, how many integer roots of this equation are satisfy to the...Integer root of this equation is a pair of integer numbers (x,y).
如果一个函数h，我们可以找到它在[a,b]之间的概率密度函数f (w = h / f)，则该积分等同于w的期望值。

在coursera上看了Andrew Ng的《Machine Learning》课程，里面讲到了正规方程(Normal Equation)，现在在此记录一下推导过程。
众所周知，Equation Group这一黑客团伙与美国国家安全局（NSA）的关系一直十分密切。而且外界也普遍认为，Equation Group是美国国家安全局的一个下属部门。...很多安全研究专家表示，Equation Group这一黑客组织所拥有的技术无论是从复杂程度还是从其先进程度来看，都已经超越了目前绝大多数的黑客团体，而且该黑客组织已经活跃了二十多年了。
