This new algorithm is faster than the old one because it re-uses multinomial coefficients as much as possible. commit aa1ddc484c2a22a1ab2b38047cbd221f9b37750a Author: Richard Kreckel <kreckel@ginac.de> Date: Sat Jul 18 23:56:55 2015 +0200 Fix pow(+(...),2).expand(). Due to a failure to expand result terms, expand((sqrt(1+x)+y*sqrt(1+x))^2) returned 1+y^2+x+x*y^2+2*y*(1+x). Note that 2*y*(1+x) was not expanded to 2*y+2*y*x. ----------------------------------------------------------------------- Summary of changes: check/exam_paranoia.cpp | 13 ++ check/timer.cpp | 1 - ginac/add.cpp | 4 +- ginac/power.cpp | 384 ++++++++++++++++++++++++++++++++++++++---------- 4 files changed, 320 insertions(+), 82 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
