We call a function from to a predictor. A function is said to be constantly predicted by a predictor , if there is an such that . Let denote the smallest size of a set of predictors such that every can be constantly predicted by some predictor in . In , we showed that may be greater than . In the present paper, we will prove that may be smaller than .
