WebAug 28, 2024 · 1. It is worth keeping in mind that people's intuitions about "computable" have changed since the time the Church-Turing thesis was formulated. In Turing's time "computer" was a person. Nowadays children are surrounded by computers (machines) since an early age – of course "computable" means "computable by a computer"! – … WebAssuming it is, I'm most curious about how it impacts the Church-Turing Thesis -- the notion that anything effectively calculable can be computed by a Turing Machine. For example, it seems possible that the existence of an effective procedure for deciding whether a Turing Machine halts would contradict the First Incompleteness Theorem.
In computability theory, the Church–Turing thesis (also known as computability thesis, the Turing–Church thesis, the Church–Turing conjecture, Church's thesis, Church's conjecture, and Turing's thesis) is a thesis about the nature of computable functions. It states that a function on the natural numbers can … See more J. B. Rosser (1939) addresses the notion of "effective computability" as follows: "Clearly the existence of CC and RC (Church's and Rosser's proofs) presupposes a precise definition of 'effective'. 'Effective … See more Proofs in computability theory often invoke the Church–Turing thesis in an informal way to establish the computability of functions while avoiding the (often very long) details which would be involved in a rigorous, formal proof. To establish that a function is … See more The success of the Church–Turing thesis prompted variations of the thesis to be proposed. For example, the physical Church–Turing … See more One can formally define functions that are not computable. A well-known example of such a function is the Busy Beaver function. This function takes an input n and returns the largest number of symbols that a Turing machine with n states can print before halting, … See more One of the important problems for logicians in the 1930s was the Entscheidungsproblem of David Hilbert and Wilhelm Ackermann, … See more Other formalisms (besides recursion, the λ-calculus, and the Turing machine) have been proposed for describing effective calculability/computability. Kleene (1952) adds to the list the functions "reckonable in the system S1" of Kurt Gödel 1936, and Emil Post's … See more Philosophers have interpreted the Church–Turing thesis as having implications for the philosophy of mind. B. Jack Copeland states … See more WebChurch-Turing Thesis (SCT), the widespread belief that Turing Machines (TMs) capture all computation, so models of computation more expressive than TMs are impossible. In this paper, we show that SCT reinterprets the original Church-Turing Thesis (CTT) in a way that Turing never intended; its commonly assumed equiva-lence to the original is a myth.
WebJan 5, 2024 · This is exactly the P vs NP question. NP-complete problems can be solved in polynomial time iff P=NP. If P ≠ NP, then all problems in NP cannot be solved in polynomial time. P is a subset of NP, so some problems in NP can definitely be solved in polynomial time. Furthermore, if we consider the Church-Turing thesis, and if P ≠ NP, then no ...

WebChurch–Turing–Deutsch principle. In computer science and quantum physics, the Church–Turing–Deutsch principle ( CTD principle) is a stronger, physical form of the Church–Turing thesis formulated by David Deutsch in 1985. [1] The principle states that a universal computing device can simulate every physical process .
WebA turing machine is a mathematical model of a computation that defines an abstract machine.
