It would indeed be interesting to have timings of giac (with the icas executable, available on my homepage at sage) and magma on the same PC. > That's interesting.

For 2 variables, clearly yes. But for 3 or more variables, it is more difficult to say since computing the gcd requires recursive call and I would also have to mesure the time used for checking in the recursive calls. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
