However, before such simulations became computationally feasible, considerable attention was given to the calculation of thermodynamic properties of clusters from the PES.
The technique is computationally efficient and allows the calculation of the properties of interacting elements.
For relatively small cases, which are computationally inexpensive, this representation can be enhanced by using the Person Shape option.
These computationally intractable sums or integrals can be avoided by using approximate Bayesian methods.
For [computationally irreducible] complex systems there is no other way to predict their evolution than by tracking it.
