How to define the step size of steepest descent method and update the step size simultaneously in multiple variable function? As following, the initial value of 2-dimensional object function are x0 and y0, but if i view { (x1’,y1’), (x2’,y2...
那么找到最底层的数学运算函数(在game/code/q_math.c), 必然是精心编写的。里面有很多有趣的函数,很多都令人惊奇,估计我们几年时间都学不完。在game/code/q_math.c里发现了这样一段代码。它的作用是将一个数开平方并取倒,经测试这段代码比(float)(1.0/sqrt(x))快4倍: float Q_rsqrt( float number ) ...
This pattern is useful when your function has some initial preparatory work to do andit needs to do it only once.In such cases, the selfdefining function can update its own implementation.eg:var selfFunc = function () { console.log("First Initialization!"); selfFunc = function () { .....
