If your random number generator is generating the same sequence of random numbers every time your program is run, you probably didn’t seed it properly (or at all). Make sure you’re seeding it with a value that changes each time the program is run. ...
Stack Overflow用户 回答已采纳 发布于2022-05-03 19:20:01 看起来调用np.random.choice(samples, p=probabilities)中的第一个参数有问题。第一个参数应该是x,而不是samples。 作者添加的: 原因是samples是曲线的值(即y轴,而不是x轴)。 因此,概率最高的值(即平均值附近的样本)都有~1的值,这就是为什么我...

随机数生成(Random Number Generation, RNG)的方式一般有两种,分别为: 硬件生成随机数Hardware RNG,原理是用某个仪器一直探测环境中的物理量,将该物理量作为随机数[2]。由于人类目前还无法对真实的物理环境进行建模,所以无从预测下一个产生的随机数是什么。因此,HRNG可以看作真随机数。
