....In Section 1.1 are informally presented what we need of the basic concepts and motivations from inductive inference including parsimony constraints on inferred (learned) programs. As we will see, degrees of parsimony will be measured with notations from Kleene s O for the constructive ordinals [Rog67] Section 1.2 presents a corresponding informal introduction with motivations and examples. Section 1.3 summarizes our principal results. These feature infinite hierarchies of success criteria re inferring parsimonious programs, and they are based on O measured degrees of parsimony. Section 2 ....
....compute f(x) and decode) The trial and error aspect of algorithmically learning such explanatory programs p models that the scientific community changes its mind over time as to explanations for a phenomenon. Informally, acceptable programming systems (synonym: acceptable numberings) Rog58, Rog67, MY78, Roy87] are those programming systems for the partial computable functions which are intercompilable with naturally occurring general purpose programming formalisms such as Turing machine formalisms and the LISP programming language. The programs output by inductive inference algorithms ....

....j. By convention, x, y, range over finite sequences of numbers, the length of which will always be clear from context. We will freely pun between x 2 N as a number and a 0 1 string. Let h Delta; Deltai be a standard, poly time computable pairing function, e.g. the one from Rogers [Rog67]. By convention, for each n 2 and each x 1 ; xn 1 2 N, we recursively define hx 1 ; xn 1 i = def hx 1 ; hx 2 ; xn 1 ii. Encoding lists. For each x; y 2 N, let x Pi y denote the concatenation of (the dyadic representations of) x and y. For each x 2 N, let E(x) 1 jxj 0 ....
....less; and f = g means g 2 FV(f ) Programming systems. We say that a partial recursive : N N is a programming system for a class of functions S PR if and only if S = f x (i; x) i 2 N g. We typically write i (x) for (i; x) We say that is an acceptable programming system of S [Rog67,RC94] if and only if it is the case that for any other programming system for S, say , there is a recursive function t such that, for all i, t(i) i , that is, there is an effective way of translating (or reducing) programs into equivalent programs. Let be an acceptable programming system ....

....The trigger of ae is the tuple (l 1 ; l ar(f) with l i = a i if i 2 I and l i = otherwise. We say that a signature Sigma is decidable if there is an algorithm that answers yes if the input is the encoding of a function symbol in Sigma, and no for all other inputs (see, e.g. [186]) The following classification of De Simone languages, and the subsequent result, stem from [101] Definition 5.14 (Properties of De Simone languages) A De Simone language over a signature Sigma is: ffl recursively enumerable if Sigma is decidable and the set of De Simone rules is recursively ....

....in computer science, even strict ones, it is possible to show local coalescence, where membership in some class of the hierarchy and in its complementary class implies membership in a lower class. For example, RE co RE = Rec describes coalescence at the bottom of the arithmetical hierarchy [Rog67]. On the other hand, the analogous coalescence for the polynomial hierarchy is not known; it is a major open question whether NP co NP = P [GJ79] In [KV01] we showed that the bottom levels of the calculus expressiveness hierarchy coalesce: 1 1 ML. In other words, if we can express a ....

But this conclusion contradicts the undecidability of K. This example indicates that our simulation definitions are strong ....
