What is verlet integration used for?

Verlet integration (French pronunciation: ​[vɛʁˈlɛ]) is a numerical method used to integrate Newton's equations of motion. It is frequently used to calculate trajectories of particles in molecular dynamics simulations and computer graphics.

Is verlet algorithm a self starting algorithm?

Its advantage is that in general does a better job of maintaining energy conservation. However, the Beeman algorithm is not self-starting.

What could be an advantage of the velocity verlet algorithm over the classical verlet algorithm?

The advantage of this form of the velocity Verlet algorithm is that it requires less computer memory, because only one set of positions, forces and velocities need to be carried at any one time. This convenience is not apparent in the original equations.
