This generator is based on acceptance-rejection technique, however, in theory, when the number of rectangle preponderates over 255, the acceptance probability is higher than 99.1%, with 98% of the time the required random variable is produced simply by doing a multiplication.

该算法基于接受－拒绝抽样技术，理论分析表明当矩形数大于255个时，该算法的抽样效率大于99.1%，而且98%以上的时间内仅需进行一次简单的乘法运算。
