## Why is the Colossus of Rhodes a wonder of the ancient world?

The Colossus of Rhodes was one of the Seven Wonders of the Ancient World. It represented the god Helios, and was built to thank the gods for the victory over Demetrius Poliorcetes’ long siege (305 BCE) of Rhodes. The Colossus of Rhodes is familiar to almost everyone.

## Who proved that a machine capable of processing?

Alan Turing

## What did Turing prove?

Turing’s proof is a proof by Alan Turing, first published in January 1937 with the title “On Computable Numbers, with an Application to the Entscheidungsproblem.” It was the second proof (after Church’s theorem) of the conjecture that some purely mathematical yes–no questions can never be answered by computation; more …

## What is difference between restricted Turing Machine and Universal machine?

A universal Turing machine is just a Turing machine whose programming simulates other Turing machines. That is, the input to the UTM is a description of a Turing machine T and an input for T, and the UTM simulates T on that input. If you like, a UTM is an interpreter for (all) Turing machines.

## What are the applications of Turing machine?

Turing machines founds applications in algorithmic information theory and complexity studies, software testing, high performance computing, machine learning, software engineering, computer networks and evolutionary computations.

## Which is not application of Turing machine?

## Can a Turing machine act like a transducer?

A Turing machine can be used as a transducer. The most obvious way to do this is to treat the entire nonblank portion of the initial tape as input, and to treat the entire nonblank portion of the tape when the machine halts as output.

## Why we use Turing machine in automata?

The main advantage of the Turing machine is we have a tape head which can be moved forward or backward, and the input tape can be scanned. The simple logic which we will apply is read out each ‘0’ mark it by A and then move ahead along with the input tape and find out 1 convert it to B.

## Who invented the universal machine?

## How does the universal Turing machine work?

In computer science, a universal Turing machine (UTM) is a Turing machine that simulates an arbitrary Turing machine on arbitrary input. The universal machine essentially achieves this by reading both the description of the machine to be simulated as well as the input to that machine from its own tape.

## Can the universal Turing machine simulate the universal Turing machine?

This is why we instroduce the notion of a universal turing machine (UTM), which along with the input on the tape, takes in the description of a machine M. The UTM can go on then to simulate M on the rest of the contents of the input tape. A universal turing machine can thus simulate any other machine.

## Can a universal Turing machine simulate itself?

7 A Universal Turing Machine can simulate the operation of any Turing machine, including itself, in polynomial time.

## Does a universal Turing machine halt on all input?

In particular, the universal TM accepts HALT, but no TM can decide HALT. There are languages which are not recursively enumerable, in particular the language NOTRE in the proof.

## Is halting a problem with NP?

– If we had a polynomial time algorithm for the halting problem, then we could solve the satisfiability problem in polynomial time using A and X as input to the algorithm for the halting problem . – Hence the halting problem is an NP-hard problem which is not in NP. – So it is not NP-complete.

## Can the halting problem be solved?

Halting problem is perhaps the most well-known problem that has been proven to be undecidable; that is, there is no program that can solve the halting problem for general enough computer programs.

## How many states a Turing machine has?

two states
