In numerical analysis, predictor–corrector methods belong to a class of algorithms designed to integrate ordinary differential equations – to find an unknown function that satisfies a given differential equation. All such algorithms proceed in two steps:
The Adams–Moulton methods are solely due to John Couch Adams, like the Adams–Bashforth methods. The name of Forest Ray Moulton became associated with these methods because he realized that they could be used in tandem with the Adams–Bashforth methods as a predictor-corrector pair (Moulton 1926); Milne (1926) had the same idea.
The pink region is the stability region for the second-order Adams–Bashforth method. Let us determine the region of absolute stability for the two-step Adams–Bashforth method y n + 1 = y n + h ( 3 2 f ( t n , y n ) − 1 2 f ( t n − 1 , y n − 1 ) ) . {\displaystyle y_{n+1}=y_{n}+h\left({\tfrac {3}{2}}f(t_{n},y_{n})-{\tfrac {1}{2}}f(t_{n ...

Crisfield was one of the most active developers of this class of methods, which are by now standard procedures of commercial nonlinear finite element programs. The algorithm is a predictor-corrector method. The prediction step finds the point (in IR^(n+1) ) which is a step along the tangent vector at the current pointer. The corrector is ...
Corrector step 1 Velocity component obtained from predictor step may not satisfy the continuity equation, so we define correction factors p',v',u' for the pressure field and velocity field. Solve the momentum equation by inserting correct pressure field p ∗ ∗ {\displaystyle p^{**}} and get the corresponding correct velocity components u ∗ ...
Mehrotra's predictor–corrector method in optimization is a specific interior point method for linear programming.It was proposed in 1989 by Sanjay Mehrotra. [1]The method is based on the fact that at each iteration of an interior point algorithm it is necessary to compute the Cholesky decomposition (factorization) of a large matrix to find the search direction.
