According to Wikipedia, the Axiom computer algebra system is licensed as New BSD.
http://en.wikipedia.org/wiki/Axiom_%28computer_algebra_system%29 It also claims that it contains Bronstein's original implementation of Risch algorithm. Does it mean that the code could possibly be copied and translated into SymPy? I'm telling you, because I see that there is an ongoing effort to implement the Risch algorithm based on Bronstein's book. If it is possible to import parts of Axiom, maybe the work would be easier. Apparently Axiom's development has split into FriCAS and OpenAxiom two years ago. -- You received this message because you are subscribed to the Google Groups "sympy" group.
