That's an interesting idea. A few professors of my school teach symbolic computation (or rather, symbolic computation software), few of them research it, that might be the reason why my professor thought Risch algorithm like that. > For algebraic functions probably most > important is work on other parts of FriCAS: we could greatly > improve speed for such integrals using better algorithms for > gcd, determinants, resultants, etc... For definite integrals > we need to improve limits. Can you elaborate more on current problems and possible improvements of these algorithms? So that I and others on this group can help to improve. One problem I know is about resultants: there are PRS, SUBRESP, NSMP, at least some cleanup is needed. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
