Integration Algorithm

• The computational effort required is a major consideration in choosing which algorithm to use.
• An algorithm that is normally more expensive (for example, requires more than one force evaluation per iteration) may permit a significantly longer time step to be used and so, in fact, may be more cost-effective.
• One of the most important considerations is the energy conservation.
  • a variation of one part in 10^4 is generally considered acceptable.
