Constraints do not follow DCP rules in CVXPY

Question

I want to solve this problem using CVXPY but I don\'t know why I get the following error message:

DCPError: Problem does not follow DCP rules.

Answer 1

Your utility function:

cvx.log(h_k_1) + cvx.log(h_k_2)

is not convex.

These rules might be able to tell you what you can sub in your solution.
