Non-linear optimizations in python?

Question

What is the best way to solve a constrained non linear optimization problem in python?

Type of problem is highly non-convex:

Maximize

A*log(1+x1)*y1 + B*log(1+x2)*y2 + C*log(1+x3)*y3

subjected to

x1*y1 + x2*y2 + x3*y3 <= K;
l1 <= x1*y1 <= u1;
l2 <= x2*y2 <= u2;
l3 <= x3*y3 <= u3;
where xi's & yi's are variables and A,B,C,K,li's & ui's are constants

Any recommendations for the solver or the API's I should explore

Definitely, checkout Scipy.optimize

The NonlinearConstraint functionality was basically designed for things like this. Just change your lambda function to include the relevant constraint

Also worth checking out these other answers:
