NettetAn implementation of this approach using standard 64-bit IEEE-754 arithmetic and the LINPACK routines for LU decomposition, with final results rounded to the nearest integer, correctly finds the vector of coefficients (1, 0, 0, 32769, 0, 0, 1), which corresponds to the polynomial function f ( x) = 1 + (2 15 + 1) x3 + x6. NettetInteger Relation Detection Let x = ( 1 ;x 2 ; n ) be a vecto r of real numb ers. Then x is said to p ossess an integer relation if there exist integers a i not all zero such that a 1 x + 2 n = 0 Problem : Find the integers a i if they exist. If they do not, obtain a sequence of b ounds on the size of any p ossible integers a i .

At the present time, the most effective algorithm for integer relation detection is the “PSLQ” algorithm of mathematician-sculptor Helaman Ferguson [10, 4]. how to earn anthem rewards
