求解rSUM问题的一个新算法

A new algorithm for solving the rSUM problem

Valerii Sopin

摘要:

一个确定的算法来解决rSUM问题的任何自然r次二次评估的时间复杂度在某些情况下。就所使用的存储器量而言,所获得的算法是nlog^3(n)阶。所获得的算法的想法是基于不考虑整数,而是在二进制记数系统中这些数字的k(是自然的)连续位。它表明,如果整数的总和等于零,那么由这些数字的任何k个连续位所呈现的数字的总和必须足够“接近”零。这使得有可能丢弃的数字,更何况,不建立解决方案。

英文摘要:

A determined algorithm is presented for solving the rSUM problem for any natural r with a sub-quadratic assessment of time complexity in some cases. In terms of an amount of memory used the obtained algorithm is the nlog^3(n) order. The idea of the obtained algorithm is based not considering integer numbers, but rather k (is a natural) successive bits of these numbers in the binary numeration system. It is shown that if a sum of integer numbers is equal to zero, then the sum of numbers presented by any k successive bits of these numbers must be sufficiently "close" to zero. This makes it possible to discard the numbers, which a fortiori, do not establish the solution.
