Remark: Maximum information is not minimum output entropy

Local one-use proof › Population-resolved output entropy · lines 598–603

The population minimizing an individual output entropy need not maximize Holevo information. In the certificate below, the former population is $1/4$ , whereas $p^{⋆} > 469/1000$ .
