Theorem von rice
In computability theory, Rice's theorem states that all non-trivial semantic properties of programs are undecidable. A semantic property is one about the program's behavior (for instance, does the program terminate for all inputs), unlike a syntactic property (for instance, does the program contain an if-then-else … Visa mer Let p be a property of a formal language L that is nontrivial, meaning 1. there exists a recursively enumerable language having the property p, 2. there exists a recursively enumerable language not having the … Visa mer According to Rice's theorem, if there is at least one partial computable function in a particular class C of partial computable functions and … Visa mer Proof sketch Suppose, for concreteness, that we have an algorithm for examining a program p and determining infallibly whether p is an implementation of … Visa mer One can regard Rice's theorem as asserting the impossibility of effectively deciding for any recursively enumerable set whether it has a … Visa mer A corollary to Kleene's recursion theorem states that for every Gödel numbering $${\displaystyle \phi \colon \mathbb {N} \to \mathbf {P} ^{(1)}}$$ of the computable functions and … Visa mer Rice's theorem can be succinctly stated in terms of index sets: Let $${\displaystyle {\mathcal {C}}}$$ be a class of partial recursive functions with index set $${\displaystyle C}$$.

Suppose the conditions of Theorem 1.1 hold, but with the addi tional assumption that there exists ρ e (0,1) such that the functions are linearly independent on [0, p] and on [ρ, 1].
