| == 2 variables over GF(43051) == File: fermat_gcd_mod_2var.py || ||ezgcd ||modular || ||p - 20 ||0.25 ||0.25 || ||q - 40 ||14.23 ||14.00 || ||r - 100 || ||- || ||s - 160 || ||- || |
These are the polynomials found on this page: http://magma.maths.usyd.edu.au/users/allan/gcdcomp.html
For the Maxima timings, I did the following:
sage: mp1 = maxima(p1) sage: mp2 = maxima(p2) sage: time a = mp1.gcd(mp2)
