Hi, I have a very complicated expression. Running simplify on it takes a long time (running for 70 h and counting), while other similar or even longer expressions have been done in a few minutes. Is it possible that it has entered an endless loop?
The expression as is is good enough for my purposes, but I wanted to report a possible bug. a0, a1, a2, b0, b1, b2, c0, c1, c2 = symbols(vector_components, real=True) angle, torsion = symbols(input_angles, real=True) length, prev_length = symbols(input_lengths, real=True, positive=True) c0 + length*((a1 - b1)*(b2 - c2) - (a2 - b2)*(b1 - c1))*sin(angle)*sin(torsion)/sqrt(((a0 - b0)*(b1 - c1) - (a1 - b1)*(b0 - c0))**2 + ((a0 - b0)*(b2 - c2) - (a2 - b2)*(b0 - c0))**2 + ((a1 - b1)*(b2 - c2) - (a2 - b2)*(b1 - c1))**2) + length*(-b0 + c0)*cos(angle)/prev_length + length*((b1 - c1)*((a0 - b0)*(b1 - c1) - (a1 - b1)*(b0 - c0)) + (b2 - c2)*((a0 - b0)*(b2 - c2) - (a2 - b2)*(b0 - c0)))*sin(angle)*cos(torsion)/(prev_length*sqrt(((a0 - b0)*(b1 - c1) - (a1 - b1)*(b0 - c0))**2 + ((a0 - b0)*(b2 - c2) - (a2 - b2)*(b0 - c0))**2 + ((a1 - b1)*(b2 - c2) - (a2 - b2)*(b1 - c1))**2)) Thanks, /David. -- You received this message because you are subscribed to the Google Groups "sympy" group.
