Integration Schemes
Solving differential equations is one of the major topics in numerical analysis. Several algorithms particularly suitable for molecular dynamics will be introduced. Runge-Kutta method
 

This is a very straightforward but less accurate method.

Verlet algorithm
 

This algorithm is particularly suited for molecular dynamics. It has been widely used in many areas from simulation of liquids and solids to biological molecules.
