Hi, I'm trying to solve this system of nonlinear equations, however after and hour it looks like it won't make it very soon.
I read up and found that solveset was the way to go into the future, however the 1.0 version if sympy that I'm using apparently doesn't have solveset.nonlinsolve(). As of now I was forced to use old regular solve. Here is my input: res=solve([expr1,expr2,expr3,expr4], [la1,la2,la3,la4],set=true) Where the first expression is like this: -0.005*lambda_1*(-1.01*lambda_1 + 2/(1 + 0.749922055929781/lambda_1))/(- 0.995*lambda_1*(lambda_1 - 1/(1 + 0.749922055929781/lambda_1)) + 0.995* lambda_1/(1 + 0.749922055929781/lambda_1) - 0.995*lambda_2*(lambda_2 - 1/(1 + 1.12753540370512/lambda_2)) + 0.995*lambda_2/(1 + 1.12753540370512/ lambda_2) - 0.995*lambda_3*(lambda_3 - 1/(1 + 1.82344707450068/lambda_3)) + 0.995*lambda_3/(1 + 1.82344707450068/lambda_3) - 0.995*lambda_4*(lambda_4 - 1/(1 + 6.27879834162764/lambda_4)) + 0.995*lambda_4/(1 + 6.27879834162764/ lambda_4) + 1.005) - 0.005*lambda_1 + 0.005*lambda_1/(-0.995*lambda_1*(lambda_1 - 1/(1 + 0.749922055929781/lambda_1)) + 0.995*lambda_1/(1 + 0.749922055929781/lambda_1) - 0.995*lambda_2*(lambda_2 - 1/(1 + 1.12753540370512/lambda_2)) + 0.995*lambda_2/(1 + 1.12753540370512/lambda_2) - 0.995*lambda_3*(lambda_3 - 1/(1 + 1.82344707450068/lambda_3)) + 0.995* lambda_3/(1 + 1.82344707450068/lambda_3) - 0.995*lambda_4*(lambda_4 - 1/(1 + 6.27879834162764/lambda_4)) + 0.995*lambda_4/(1 + 6.27879834162764/lambda_4) + 1.005) Maybe I should try a numeric solve, but in an ideal world some of this numbers are variables, I'm just trying to solve first for a particular case. Is there a way to maybe optimize this? Any help is greatly appreciated, as this is for my thesis xd -- You received this message because you are subscribed to the Google Groups "sympy" group.
