Binary gcd algorithm

WebGiven integers x and y, Algorithm 2.107 computes integers a and b such that ax + by = v, where v = gcd(x, y). It has the drawback of requiring relatively costly multiple-precision divisions when x and у are multiple-precision integers. Algorithm 14.61 eliminates this requirement at the expense of more iterations. Webfinds the binary matrix, which matches the DFT coefficientX˜ 11 in the reduced search space with given column and row sums. As this is a larger system with binary integer bounds, it is generally more efficient to solve by using ILP. This is summarized inAlgorithm 1. Algorithm 1 Reconstruction algorithm for N 1 ×N 2 binary matrices where N 1 ...
