My random number generator has an optional integer argument, if present it uses this as the seed. If not present it calls system_clock(i) and uses i as the seed. So far so good. However if the Random_Number_routine is called too quickly, more than once a second, th...

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...
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-randomnumbergenerator，QRNG）[4]能够生成稳定、低差异性的（low-discrepancy）样本，而与样本数目或空间维数无关[5]。故针对蒙特卡罗积分结果不稳定的情况，提出一种基于QRNG的蒙特卡罗积分，发现比传统方法性能有所提升。 伪随机数介绍 伪随机数是由...
