|The generalized Poor-Verdu error lower bound for multihypothesis testing is revisited. Its asymptotic expressionis established in closed-form as its tilting parameter grows to infinity. It is also shown that the asymptotic generalized bound achieves the error exponent (or reliability function) of the memoryless binary symmetric channel at zero coding rates.
