Chapter-3 provides a complete idea of the Predictor-Corrector method. Derivation of Milne's Predictor-Corrector formula and Adams-Moulton Predictor-Corrector formula with their local truncation ... Because the present method has greater stability limits than Adams-Moulton predictor-corrector methods, the proposed method has good robustness during the process of time integration. A crank-slider mechanism is used as an example to investigate the capability of the proposed method in solving multibody dynamic systems. Code, Example for MILNE'S METHOD in C Programming.

Adams methods are based on the idea of approximating the integrand with a polynomial within the interval (t n, t n+1). Using a k th order polynomial results in a k +1th order method. There are two types of Adams methods, the explicit and the implicit types. The combination of evaluating a single explicit integration method (the predictor step) in order to provide a good initial guess for the successive evaluation of an implicit method (the corrector step) using iteration is called predictor-corrector method. The motivation using an implicit integration method is its fitness for solving stiff problems.
