Hello everybody !!!! Concerning the use of InfinitePolynomialRing in Sage, it was discussed in another thread and I since wrote a patch (#7561) to change it. As mentionned, I need nothing of what this class has been built for, and now that it is replaced with plain "var", it is a thousand times faster ( a friend of mine needed to solve a LP with ~2000 variables and could not even generate the LP because of this slowness in InfinitePolynomialRing.
Besides the slowness, there was a bug coming for InfinitePolynomialRing which I have not been able to reproduce yet ( the reason why there was no bug report for it ) when the LP got big enough :some "string" problem prevented us from using the generators anymore, and restarting Sage ( ? ) sometimes solved the problem. If I can produce this bug again, you'll have a bug report for it, but I you know the class by heart perhaps you will be helped to know that you need a large number of variables to create this problem.
