Abstract --- A formula for the optimistic capacity of
arbitrary channels is established. It is shown to equal
the supremum, over all input processes, of the input
output zerosupinformation rate. A general expres
sion for optimistic ''capacity is also provided.
The conventional definition of channel capacity C  requires
the existence of reliable block codes for all sufficiently large
