The church-turing thesis states that everything that can physically be computed, can be computed on a turing machine the paper analog computation via neural networks (siegelmannn and sontag, theoretical computer science, 131:331–360, 1994 pdf) claims that a neural net of a certain form (the settings are presented in the paper) is more powerful.

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 hypothesis about the nature of computable functions.

Ca320 - computability & complexity introduction david sinclair introduction overview in this module we are going to answer 2 important questions: church-turing thesis • computability. Church then turing identified the computational core of the incompleteness theorem, and were able to produce undecidable problems this work, along with gödel's work on general recursive functions, established that there are sets of simple instructions, which, when put together, are able to produce any computation. Recursive function, in logic and mathematics, a type of function or expression predicating some concept or property of one or more variables, which is specified by a procedure that yields values or instances of that function by repeatedly applying a given relation or routine operation to known values of the function.
