Is Minecraft Redstone Turing complete?

5 Answers. I know this question is a bit old, but all the other answers seem quite complex to me, while the answer itself can be quite simple: nor gates are universal, redstone torches are nor gates, and all graphs can be embedded in 3-space; so yes, Minecraft is Turing complete!

Is context free grammar Turing complete?

These three new languages are still regular, context-free and context-sensitive, respectively, since the syntaxes have not changes. But none of them is Turing complete.

Can a programming language not be turing complete?

Turing completeness is used as a way to express the power of such a data-manipulation rule set. Virtually all programming languages today are Turing-complete. No physical system can have infinite memory, but if the limitation of finite memory is ignored, most programming languages are otherwise Turing-complete.

What is required for a language to be Turing complete?

In general, for an imperative language to be Turing-complete, it needs: A form of conditional repetition or conditional jump (e.g., while , if + goto ) A way to read and write some form of storage (e.g., variables, tape)

Is there a non regular language that you can decide with a Turing machine?

Whether a language is regular or not is a semantic property – having to do with what’s in the language, not with the form of the Turing machine – so, by Rice’s theorem, it cannot be decided whether L(M) is regular.

Can a Turing machine decide if a language is context-free?

Context Free languages (CFLs) are languages that are recognised by Context Free Grammars, i.e., grammars whose production rules are of the form N → (N ∪ Σ)⇤. They are also languages that are recognised by a type of machine called Pushdown automata. Every CFL can be decided by some Turing Machine.

How do you prove something is Turing-complete?

Typically, one proves a given language is Turing-complete by providing a recipe for translating any given Turing machine program into an equivalent program in the language in question. Alternately, one can provide a translation scheme from another language, one that has already been proven to be Turing-complete.

How do I know if my 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/\%CE\%9C-recursive_function can be computed by the programming language.
