素性检验的新方向

New Directions for Primality Test

Lakshmi Prabha S, T. N. Janakiraman

摘要:

本文给出了两种近似算法。设N是奇合数。这些算法为给定N的素性检验提供了新的方向。第一种算法是用一种新的方法--数字编码法给出的。证明了该算法在至多O(ln^{4} N)内找到N的除数,其中ln表示以2为底的对数。该算法可用于寻找下一个最大的梅森素数。关于这一点给出了一些指示。第二种算法利用图偶的概念求N的一个素除子,并证明了在无限多种情况下(N近似大),第二种算法的时间复杂度至多为O(ln^{2} N).分析了第二种算法的优缺点。

英文摘要:

In this paper, two approximation algorithms are given. Let N be an odd composite number. The algorithms give new directions regarding primality test of given N. The first algorithm is given using a new method called digital coding method. It is conjectured that the algorithm finds a divisor of N in at most O(ln^{4} N), where ln denotes the logarithm with respect to base 2. The algorithm can be applied to find the next largest Mersenne prime number. Some directions are given regarding this. The second algorithm finds a prime divisor of N using the concept of graph pairs and it is proved that the time complexity of the second algorithm is at most O(ln^{2} N) for infinitely many cases (for approximately large N). The advantages and disadvantages of the second algorithm are also analyzed.
