Optimal Codes for Minimax Criterion

This is closely tied to the minimum weight to length ratio of cycles in the diagram, which is not obviously directly dependent on m. This observation should also be true about T,,,~” in Hemmati and Costello [3], though 7min is of the order of four to six times m for the examples they consider. The fact that low weight cycles in the state diagram cause the requirement that the guard space be large is consistent with the fact that codes which are catastrophic have state diagrams which contain a nontrivial zero weight cycle. Finally, we would like to observe that there are good reasons to view an error pattern as beginning as usual when the first incorrectly transmitted digit is received, but not ending until the decoder has returned to an e-ready state.
