Теорема Райса — утверждение теории алгоритмов, согласно которому для любого нетривиального свойства вычислимых функций определение того, вычисляет ли произвольный алгоритм функцию с таким свойством, является алгоритмически неразрешимой задачей. Википедия
Rice theorem states that any non-trivial semantic property of a language which is recognized by a Turing machine is undecidable. |
Rice's theorem: Any nontrivial property about the language recognized by a Turing machine is undecidable. A property about Turing machines can be ... |
• Rice's theorem says nothing about properties of Turing machines. • Rice's theorem says nothing about whether a property of languages is recurisvely enumerable. |
To our knowledge most proofs of Rice's Theorem are based on a reduction of the halting problem (or other unsolvable problem) to an eventual al- gorithm that ... |
Rice's Theorem helps identify languages which are not decidable. Specifically, it helps identify undecidable languages which are subsets of T. |
1 мая 2023 г. · Rice's theorem states that any nontrivial property of a Turing machine's output is undecidable. In other words, there is no general algorithm ... |
Rice's theorem says that undecidability is the rule, not the exception. It is a very powerful theorem, subsuming many undecidability, results that we have seen ... |
Thus, as per Rice's theorem the language describing any nontrivial property of Turing machine is not recursive. It can either be recursively enumerable or not ... |
