Comments on "A source matching approach to finding minimax codes" by Davisson, L. D. and Leon-Garcia, A.
Boris Ya. Ryabko · IEEE Transactions on Information Theory · 1981
In the above paper^{1}Davisson and Leon-Garcia prove a result equating the minimax redundancy for universal codes to a channel capacity that is computable by standard techniques. They point out that the result had been developed earlier in unpublished work by Gallager. I would like to point out an alternative development of this result and to compare this work with that of Davisson and Leon-Garcia.
