comment Is the optimum of this problem unique?
I know that, but how is the minimum dependent on $a_i$s and $b_i$s?

comment Poisson processes and coin flips
I guess by 'flipped', he means tossed and not simply turned upside down. Not sure though, but the first sentence says "is flipped and lands on...". In that case, the answer would remain $p$.

comment Proving a function of matrix is convex
Thanks Michael. I get the determinant of the Hessian to be $-\frac{y^2}{(a-1)^4}$, which is negative?

comment Proving a function of matrix is convex
I meant $f$ is a function of both $A$ and $b$. However I am struggling even with the case when $f$ is only a function of $A$.

comment Joint distribution of arrival times in Poisson process
Thanks Did. I guess it would be $f_{S_A}(t_1)\times f_{S_B}(t_2-t_1)$, with the $S_A$ being Erlang. Correct?
