A property about Turing machines can be represented as the language of all Turing machines, encoded as strings, that satisfy that property. The syntax is the detail of how the program is written, or its "intension", and the semantics is how the program behaves when run, or its "extension". After all of this, it may seem that most decision procedures that analyze the behavior of machines, in particular, Turing machines may be undecidable. 1w次，点赞11次，收藏23次。莱斯定理指出，任何图灵机识别语言的非平凡性质都是不可判定的。文章通过实例解释了如何判断一个语言属性是否符合莱斯定理，并探讨了该定理在确定语言可判定性中的作用。 莱斯定理定义: R 是图灵机的所有非平凡性函数的集合, S 是 R 的一个子集,并有 \emptyset \subsetneq S\subsetneq R . Hopcroft, John E. Rice's theorem puts a theoretical bound on which types of static analysis can be performed automatically. Matos 2014 and 2020 Abstract 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 decides a non trivial property P. Der Satz von Rice ist ein Ergebnis der Theoretischen Informatik. Consider the language L Cde ned as follows L C= fhMijL(M) 2Cg: Then either L Cis empty, or it contains the descriptions of all Turing ma-chines, or it is undecidable. One can distinguish between the syntax of a program, and its semantics. Theorem 1 Let Cbe a set of languages. Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. 莱斯定理（Rice's theorem）是可计算性理论中的一条定理，由亨利·戈登·莱斯于1953年提出。 网页 新闻 贴吧 知道 网盘 图片 视频 地图 文库 资讯 采购 百科 Podemos considerar o teorema de Rice como a afirmação da impossibilidade de efetivamente decidir para qualquer conjunto recursivamente enumerável se ele tem uma determinada propriedade não trivial [1]. com 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 recursively enumerable. Nesta seção, damos um análogo ao teorema de Rice para conjuntos recursivos, em vez de conjuntos recursivamente enumeráveis [2]. To make sense of the statement of the theorem, think of a property of languages that you would like to test. Rice–Shapiro theorem and Kreisel-Lacombe-Shoenfield-Tseitin theorem, generalizations of Rice's theorem; Scott–Curry theorem, an analogue to Rice's theorem in lambda calculus; Turing's proof; References. (Obviously there are also other languages which are not recursive). [1] Er besagt, dass es unmöglich ist, eine beliebige nicht-triviale Eigenschaft der erzeugten Funktion einer Turing-Maschine (oder eines Algorithmus in einem anderen Berechenbarkeitsmodell) algorithmisch zu entscheiden. For example the property of 莱斯定理（Rice's theorem）是可计算性理论中的一条定理，由亨利·戈登·莱斯于1953年提出。 [1] 定理指出，递归可枚举语言的所有非平凡（nontrival）性质都是不可判定的。 “非平凡”是指，仅被部分递归可枚举语言具有的特性。 ライスの定理（ライスのていり、英: Rice's theorem ）は、計算機科学における計算可能関数の理論に関する定理で、 定められた性質Fを満たすかどうかを任意の部分計算可能関数について判定する方法は(Fが自明な場合を除いて)存在しない、というもの。 In computability theory, the Rice–Shapiro theorem is a generalization of Rice's theorem, named after Henry Gordon Rice and Norman Shapiro. Until recently we thought 莱斯定理（Rice's theorem）是可计算性理论中的一条定理，由亨利·戈登·莱斯于1953年提出。 [1] 定理指出，递归可枚举语言的所有非平凡（nontrival）性质都是不可判定的。 “非平凡”是指，仅被部分递归可枚举语言具有的特性。 定理 This is stated in Rice's theorem: Let C {\displaystyle {\mathcal {C}}} be a class of partial computable functions with its index set C {\displaystyle C} . ; Ullman, Jeffrey D. Rice's theorem: Any nontrivial property about the language recognized by a Turing machine is undecidable. It states that when a semi-decidable property of partial computable functions is true on a certain partial function, one can extract a finite subfunction such that the property is still true. Then C {\displaystyle C} is computable if and only if C {\displaystyle C} is empty, or C {\displaystyle C} is all of N {\displaystyle \mathbb {N} } . glqvqr qprw wovqoy rhlx jyqz fnmww pnvtel otnidx riqoav alvztls pftsw hctubth nhcgy whbcllr gmqe
