| Nov 4, 2016 at 15:13 | comment | added | CodeGolf | @FedorPetrov If $\epsilon=0$, it turns to prove that $G(x)+h(x)(y-x)\ge G(y)$ and taking $h$ to be the derivative of $G$ will work, i.e. $h(x)=G'(x)$. | |
| Nov 4, 2016 at 15:13 | comment | added | CodeGolf | @FedorPetrov Thanks a lot for the reply. Indeed, there is a mistake in my question: it should be $h(x)$ instead of $h$. I reformulated the question. | |
