Is human brain a Turing machine?

In the extreme case a human brain could be nothing but a device which mindlessly produces all possible algorithms. One can in fact build a machine which does this, but this machine would not be Turing complete.

Is the brain a nondeterministic Turing machine?

Strictly, the answer is “No”. The definition of a Turing Machine requires an infinite tape. Our brains don’t have infinite storage capabilities (at least to the best of our scientific knowledge). Therefore, the brain is *not* a Turing Machine.

Are humans Turing complete?

A Turing machine is a tuple consisting of an alphabet, a tape, some transition, etc. I am not one of those. So no. A human being is not a Turing machine (or at least, I am not).

How is the mind like a Turing machine?

The brain is at least a Turing machine, because a brain is capable of imagining a list of numbers, and, depending on the number at a particular point, moving backward or forward in the list and/or changing that number.

Are humans more than Turing complete?

Single human can’t solve the same class of problems that Turing machine can. If computers are Turing complete, then humans are, too. Computers do not have infinite memory, yet they are usually considered Turing complete because theoretically you could keep adding additional memory when needed.

Is the brain computable?

“The brain is not computable and no engineering can reproduce it,” says Nicolelis, author of several pioneering papers on brain-machine interfaces. “There are a lot of people selling the idea that you can mimic the brain with a computer.”

Which is more powerful deterministic Turing machine or non deterministic Turing machine?

Non-determinism is more powerful than determinism for pushdown automata. Quite surprisingly, the deterministic and non-deterministic Turing machines are the same in power. Note: If a nondeterministic Turing machine accepts a language L, then there is a deterministic Turing machine that also accepts L.

What makes something Turing-complete?

A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory). So, if somebody says “my new thing is Turing Complete” that means in principle (although often not in practice) it could be used to solve any computation problem.

Is the mind computable?

What is a Turing machine psychology?

Turing machines provide a good psychological model of at least one part our mental life: deliberate, serial, rule-governed inference – the capacity at work inside the head of the human clerk when he is solving his mathematical problems.

Is a human brain a Turing machine?

A brain is a Turing machine (aka universal computer) if and only if Turing machines can emulate brains, and brains can emulate Turing machines. The second is obviously true, a person can step through a computer program and predict what will happen, just far slower than the computer.

Is it possible to build a Turing complete computer?

One can in fact build a machine which does this, but this machine would not be Turing complete. Regarding a brain simulating a processor, I highly recommend that you read Turing’s original paper, keeping in mind that in 1936 “a computer” was a person performing computations.

Could a human brain be a machine?

In the extreme case a human brain could be nothing but a device which mindlessly produces all possible algorithms. One can in fact build a machine which does this, but this machine would not be Turing complete.

When is a language considered Turing complete?

So: a language is Turing complete if it can be simulated by Turing machines and can simulate Turing machines. We would still have to precisely explain what “simulate” means here. Languages such as C, C++ and Java are not “considered” Turing complete.
