Can someone help me with
c/y^2*e^{-ax+b} \leq z in CVX, where x,y,z are variables, and a,b,c\geq0?
I’ve checked the hessian matrix of the LHS, which is positive semidefinite.
But I encountered the Disciplined convex programming error: Cannot perform the operation: {convex} .* {log-affine} when I implement it in CVX.
I think I found a way to manage it by expressing it as ce^{-ax+b-2log(y)}, which is acceptable by CVX.
Is this a good approach?
Btw, can someone kindly explain why the original form is not accepted while the second one is?
The first formulation violates CVX’s rules.
The second formulation complies with CVX’s log-convexity rules, which unfortunately are not documented in the CVX Users’ Guide, but are documented in
