然而,目前的伪随机数生成器(Pseudo-random number generator,PRNG)[2]存在一个重要缺陷,即样本分布与真实分布不一致,这主要发生在以下两种情况:①抽样代价过高,样本数目较少;②空间维数较高[3]。 因此,有必要寻找一类新的随机数发生器。准随机数发生器(Quasi-random number generator,QRNG)[4]能够生成稳定、低...

Pseudorandom numbers are generated by deterministic algorithms. They are "random" in the sense that, on average, they pass statistical tests regarding their distribution and correlation. They differ from true random numbers in that they are generated by an algorithm, rather than a truly random proc...
