This paper starts by considering the minimization of the Rényi divergence subject to a constraint on the total variation distance. Based on the solution of this optimization problem, the exact locus of the points (D(QIIP1), D(QIIP2)) is determined when P1, P2, and Q are arbitrary probability measures which are mutually absolutely continuous, and the total… (More)
