Today, after installing Maple 13, I tested it against the Maple worksheets I use to compute versal deformations of algebras. Finally, Maple 13 is solving the systems of polynomials which Maple 9.5 could solve, but Maple 11 and 12 could not. Whatever bug in the solver was introduced in Maple 11 seems to be fixed. I will test this more extensively, but I tried it on several complex systems arising from my research and it was solving them all. Maple 11 failed even on some simple systems. In all cases, these were systems of quadratic equations, and Maple 9.5 was able to solve them all, so I had been really surprised that Maple 11 could not solve them. I appreciated all the workarounds that were posted on the Mapleprimes website, but it is nice to see that the problem was fixed finally. I just wish it had not taken more than 2 years and 2 versions of Maple to fix this problem.
