How to express exp(x).*log(1+exp(y).*inv_pos(z))?

After a quick read of the paper and a discussion with Michal Adamaszek, then we believe

  • It cannot be formulated so CVX will accept it.
  • It cannot be formulated as an exponential cone problem.

We do not have a proof of the two statements so we may be wrong. In fact we hope history will prove us wrong.
