我需要测试素数上是真正的大（在很长很长的范围内）的数字之间的间隔，所以我需要一些快速的算法，用于检查数是素与否。请提出你的想法。

I need to test primality on intervals between numbers which are really big (in the range of long long), so i need some fast algorithm for checking if a number is prime or not. Please suggest your ideas.

推荐答案

一个很好的方法是 Miller-拉宾测试。应当指出然而，这仅仅是一个概率测试

One good method is the Miller-Rabin test. It should be noted however, that this is only a probabilistic test.
