What does polynomial time actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

Here we develop a polynomial time algorithm that provably finds the ground state of any 1D quantum system described by a gapped local Hamiltonian with constant ground-state energy.

One alternative involves the use of polynomial regression equations, which permit direct tests of the relationships difference scores are intended to represent. Unfortunately, coefficients from ...

Regression models using fractional polynomials of the covariates have appeared in the literature in an ad hoc fashion over a long period; we provide a unified description and a degree of formalization ...

Dividing and factorising polynomial expressions What is a polynomial? A polynomial is an algebraic expression involving many terms and can be factorised using long division or synthetic division.

This function is a polynomial in two dimensions, with terms up to degree 5. It is nonlinear, and it is smooth despite being complex, which is common for computer experiment functions (Lim et al., 2002 ...
