Most notably Wang's multivariate factorization algorithm was implemented, so statement that "Currently multivariate factorization algorithm is based on Kronecker's method" is incorrect and obsolete. I strongly suggest you familiarize your self with SymPy's capabilities and choose algorithms and data structures that weren't implemented yet, and especially those which really make sense. For example: as SymPy already has Wang's algorithm for multivariate factorization, then it should be straightforward to implement EEZ-GCD reusing parts of the existing implementation (it would be also nice to study and implement coefficient prediction sub-algorithm of EEZ for iterations 2..n (supposed to give huge speed ups for large sparse polynomials)). If you would like to implement a different algorithm, e.g. SP-MOD, then you will have to start basically from scratch (although I would like to have implementation of this algorithm in SymPy). You will have to also provide a more detailed schedule of what you want to do and when. > > Pavel Fedotov. > > -- > You received this message because you are subscribed to the Google Groups > "sympy" group. > To post to this group, send email to sympy@googlegroups.com. > To unsubscribe from this group, send email to > sympy+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/sympy?hl=en. > > Mateusz -- You received this message because you are subscribed to the Google Groups "sympy" group.
