推荐答案
Donald Knuth开创性的整个第一章 符号算法涉及到该主题随机数生成.我真的不认为SO答案会接近描述所涉及的问题.阅读这本书.
The entire first chapter of Donald Knuth's seminal work Seminumerical Algorithms is taken up with the subject of random number generation. I really don't think an SO answer is going to come close to describing the issues involved. Read the book.
