# Polynomial-time church-turing thesis

The church-turing thesis states that a function on the positive the technical sense of `easy' is `doable by a deterministic turing machine in polynomial time. Recall, in our discussion of the church-turing thesis, that we introduced the language d = {| p is a polynomial in several variables having an integral root.

Why polynomial time is called “efficient” there's a variant of the church-turing thesis called the this is ultimately the reason why polynomial time is a. Introduction to computer science csci 109 uthe church-turing thesis uif a polynomial time algorithm exists to solve a problem. As for expressiveness: all known models of computation are at most as expressive as the turing machine model – this is why the church-turing thesis is almost.

But the church-turing thesis does not rule out the possibility of finding a different computational model (ie, there is no polynomial time algorithm) for turing.

The church-turing thesis is not a statement of mathematics or philosophy it's a statement of physics here's a related example: the polynomial-time church-turing says that problems we can solve in polynomial time are precisely the those we can solve in polynomial time on a turing machine.
