趁周末,看了看数学版的项目内容,怎么觉得算数字的很多啊.....而且,越发搞不清楚是否重复的很多了....本人数学很烂,求指教~
希望能够推荐个方法来梳理一下
普罗斯素数 Proth prime
具有 k.2 n+1 形式的素数(约束条件:2n > k)

SOB:
对于正整数k,如果它满足对于所有正整数n,k*(2^n)+1均为合数,这样的k就被称为Sierpinski数。

Riesel Sieve:
对于正整数k,如果它满足对于所有正整数n,k*(2^n)-1均为合数,这样的k就被称为Riesel数。
梅森素数 Mersenne number
形如2^p-1的正整数,其中p是素数,常记为Mp。若Mp是素数,则称为梅森素数。
此外,
PrimeGrid的任务:
Prime Numbers are of great interest to mathematicians for a variety of reasons. Primes also play a central role in the cryptographic systems which are used for computer security. Through the study of Prime Numbers it can be shown how much processing is required to crack an encryption code and thus to determine whether current security schemes are sufficiently secure.
PrimeGrid is currently running three sub-projects:
* Primegen: generating a public sequential prime number database.
* Twin Prime Search (testing): searching for gigantic twin primes of the form k*2^n + 1 and k*2^n - 1.
* Cullen-Woodall search (testing): searching for gigantic primes of forms n*2^n + 1 and n*2^n - 1.
因此,当前项目有Primegen、Twin prime search、Cullen prime search、Woodall prime search共四个。
