why (x)^2/min(2,sqrt(x3)) is a convex function?
I recently watched a YouTube video titled “Stanford EE364/A Convex Optimization Stephen Boyd I 2023 I Lecture 4.” I’m having trouble understanding one of the examples Professor Boyd discussed regarding preserving convexity. Specifically, it pertains to the function z^2/y, which is a known convex function.
convexity of the function e^(2x)/(1+e(x))
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.
