Hi, I have read your paper and very interested in it. But there is someplace (from Eq.2 to Eq. 4), which I am confused about your formula derivation. You noted that $\belta$ is not important to estimate, moreover it relies on the estimation of $\gamma$. Can you give a more specific physical explanation, why is this OK and works? Besides, why can't solve the two variables optimization in Eq. 2 directly?
