¿Cómo se prueba si un lenguaje está completo en Turing?

How do you test if a language is Turing-complete?

One way determine whether a programming language is Turing complete is to write a Turing machine in it (or an implementation of the Lambda calculus). Another way is to prove that all mu-recursive functions http://en.wikipedia.org/wiki/Μ-recursive_function can be computed by the programming language.

Most modern programming languages (e.g. Java, JavaScript, Perl, etc.) are all Turing complete because they each implement all the features required to run programs like addition, multiplication, if-else condition, return statements, ways to store/retrieve/erase data and so on.

Since it does not allow nonterminating computation, Coq is necessarily not Turing-complete.

A programming language is Turing complete if it equivalent to a Turing machine. In practice, it means that any algorithm can be implemented. Apparently, HTML5 + CSS3 is now also Turing complete because it can be used to program a Rule 110 automaton. …

Programming languages are similar to those machines (although virtual). They take programs and run them. Now, a programing language is called “Turing complete”, if that it can run any program (irrespective of the language) that a Turing machine can run given enough time and memory.

Turing completeness. In computer science, Turing completeness is a classification for a system of rules that manipulate data. It is named after computer scientist Alan Turing , inventor of the Turing machine. For instance, programming languages and CPU instruction sets are examples of formal rule systems that access and modify data.

A Turing complete is a feature that enables computer language or a platform to perform any kind of computation. It is assumed that to perform such computation there exists infinite resources available such as CPU and MEMORY.
