Minimum expected value over all probability functions












0












$begingroup$


Find the minimum value of $E[X]$ over all probability density functions f(x) satisfying the following three constraints:



(I) $f(x) = 0 $ for $x leq 0$



(II) $ int_{-infty}^{infty} f(x) dx = 1 $



(III) $h(f) = h$



Thanks!

    Can you elaborate what's $h(f)$ and $h$?

    That is the problem 22 of chapter 12 from Tomas cover information Theory. I think it's a functional
