Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

Both Church’s and Turing’s proof have been verified several times and shown to be logically valid. They are both formulations of Godel’s Incompleteness theorem, another well-understood mathematical theory. Proving Church-Turing via ASM?

Introductions to dissertations

the best argumentative essay topics - A Turing machine provides a formal definition of a "computable" function, while the Church-Turing-Thesis says that intuitive notion of "computable" coincides with the formal definition of "computable", i.e., all functions computable by TMs. This is just a hypothesis, and it is up to you to believe or not. The first headway into answering this question was made by computer science pioneers Alonzo Church’s and Alan Turing’s formalizations of computation 5 6 and the subsequent formulation of the Church-Turing hypothesis. Properly interpreted as a qualitative proposed law of nature, this hypothesis states that any process occurring in nature can be simulated by a Turing machine, . One approach to prove Church-Turing thesis as a law of physics relies on assuming a specific property of the physical world, presented as dual of the limitation on the speed of light and information, which is a limitation on the space density of information, both limitations together ensuring density limitation in space-time. dissertation research question

Various attributes of natural number theory have long been considered achievable by arbitrary functions. N. The proof goes like this: For a fixed x0, the function hx0(y) = f(x0, y) is computable (this I agree with) and so there exists an index ex0 so that hx0 = Φex0 (this I also agree with). So, the function g that to each natural x assigns such index ex (so that hx = Φg (x)) is computable (this is the part I don't understand). One of the beautiful pieces of work in theoretical computer science. Church and Turing came to the same conclusion in different areas and only later was it demonstrated they were really the same thing. They each proposed a model of computability. bold dissertation editing

There is a consensus that, in fact, neither Gödel's nor Church's formalisms were so perspicuous or intrinsically persuasive as Alan Turing's analysis, and Wilfried Sieg has argued that the evidence in favor of Church's Thesis provided by the "confluence of different notions" (the fact that the systems proposed by Church, Gödel, Post and Alan Turing all turned out to have the Estimated Reading Time: 9 mins.

Undecidability of halting problem seems to be based on the validity of the above hypothesis, which means if the thesis happens to be false, then halting problem may turn out to be computable. For example, let's consider the diagonalization proof for Halting Problem. In a proof-sketch added as an "Appendix" to his paper, Turing showed that the classes of functions defined by λ-calculus and Turing machines coincided. However, although Church's claim predated Turing's, it was Turing who, in the opinions of Gödel and others, finally gave a convincing argument for why these functions really contained all functions that one would be .

dissertation litterature terminale - A Brief Note on Church-Turing Thesis and R.E. Sets A function, f, is said to be partial recursive if there is a ’-program for it. Theorem 1 There is a total function that is not recursive. Proof: Define f as follows: for every x 2 N, f(x) = ’x(x)+1 if ’x(x) #; 0 if ’x(x)": It is clear that f is total. We shall prove that there is no ’-program for contradiction. In books on computability theory it is common for the text to skip details on how a particular machine is to be constructed. The author of the computability book will mumble something about the Turing-Church thesis somewhere in the beginning. Quantum computers will indeed show that The efficient Church-Turing thesis is invalid (modulo some computational complexity mathematical conjectures, and modulo the "asymptotic interpretation"). I think the efficient Church-Turing conjecture was first formulated in by Wolfram, the paper is cited in Pitowsky's paper linked above. where should your thesis statement be in the introduction

As I understand, the Church-Turing thesis provides a pretty clear description of the equivalence . order language, the Church-Turing thesis follows as a special case of G ö del ’s completeness theorem (first-order algorithm theorem). I propose this idea as an alternative foundation for the Church-Turing thesis, both for human and machine computation.

If pre-theoretic computation is subject to open texture, then no particular expression of it fully captures its content, and hence no first-order expression does so.

The thesis is not a mathematical statement and therefore it is not possible to prove it (in the usual mathematical sense). Instead we should view the thesis as a scientific hypothesis. In computability theory, the Church–Turing thesis (also known as the Church–Turing conjecture, Church's thesis, Church's conjecture, and Turing's thesis) is a combined hypothesis ("thesis") about the nature of functions whose values are effectively calculable; or, in more modern terms, functions whose values are algorithmically computable.
