.... 11. As #(w, b) is exactly computable in time O( w ) the proposition holds. The following proposition allows us to only be concerned with individual languages when investigating the dimension of a class. This proposition is similar to one given by Ambos Spies, Merkle, Stephan, and Reimann [2]. be a class of languages and let r N. If for each A there is some predictor #A computable in O(n ) time such that (# A , A) s, then dim p (C) s. Analogously, if for each A there is a predictor #A computable in O(n ) time satisfying str (# A , A) s, then s. ....

....of Hausdor# dimension, including constructive, computable, polynomial space, polynomial time, and finite state dimensions. Work by several investigators has already used these e#ective dimensions to illuminate a variety of topics in algorithmic information theory and computational complexity [20, 21, 1, 7, 27, 16, 15, 11, 13, 14, 10]. See [26] for a survey of some of these results. This work has also underscored and renewed the importance of earlier work by Ryabko [28, 29, 30, 31] Staiger [37, 38, 39] and Cai and Hartmanis [5] relating Kolmogorov complexity to classical Hausdor# dimension. See Section 6 of [21] for a ....

A language, or decision problem, is a set A 1 # .
