I want to solve a polynomial over ring. However my code does not work. N=8 R.=Integers(N)[] f=x^2-1 print f.roots() In my case, N is always a power of 2. -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe from this group and stop

Hi guys - I am sure that there is much more available. But actually William you hit the nail on the head. The page I used was "a small undergraduate student project" and its contents are useful and accessible. That is the level I want - so a student or someone like me can use Sage in place of

Dmitrii, Thanks very much. Sorry for the dumb posting. I should have mentioned in my posting that I'm just getting into MILP in Sage. Would it be equally dumb to post a question asking if there is an arbitrary precision real arithmetic solver for MILP in Sage? (maybe a version of GLPK?)
