Abstract
One strategy to the discrimination problem is to identify the state with ce rtainty, leaving a possibility of undecidability. This paper gives an upper bound for the maximal success probability of unambiguous discrimination am ong n states. This bound coincides with the known IDP limit when two states are considered.
