expected worst-case time complexity is O(Z*log(max(A)+max(B))2); expected worst-case space complexity is O(1), beyond input storage (not counting the storage required for input arguments). 这个比较好办,因为如果a和b是由相同的prime divisor组成,那么a/gcd(a,b)必然是gcd(a,b)的一个因子...
The time complexity is O(n), utilizing O(n)4-2 signed 1-b adders to determine the GCD of two n-b integers. The process is similar to that used in SRT division. The efficiency of the algorithm is competitive, to within a small factor, with floating point division in terms of the ...
The worst case time complexity of the proposed algorithm is O(n2) with respect to the bit-time complexity for two n-bit integers. We also proposed the parallel version of GCD algorithm. The implementation results show that the iteration required to compute GCD using ModEB algorithm are ...
