I have a problem regarding the convex function e^(2x)/(1+e(x))! While I’m calling the curvature command, it says “unknown”! So, its convexity is not recognizable by CVXPY, and I cannot use it as convex atom in my optimization.

Thanks a lot for your help.

I’ve tried several composite functions to present the function with them and make the convexity recognizable by CVXPY, but none of them work.
