The form of Dueck and Korner's exponent function for correct decoding probability for discrete memoryless channels at rates above the capacity is similar to the form of Csiszar and Korner's exponent function for correct decoding probability in lossy source coding for discrete memoryless sources at rates below the rate distortion function. We recently gave a new algorithm for computing Dueck and Korner's exponent. In this paper, we give an algorithm for computing Csiszar and Korner's exponent. The proposed algorithm can also be used to compute cutoff rate and the rate distortion function.
