The second and third interpretations may seem odd, but such assignments do create classical modal systems.

As with any ensemble of classical systems, we would like to find a corresponding probability measure on the phase space "M".

One element in a classical system cannot be changed without changing the other proportions too.

Any classical system of two particles is, by definition, a two-body problem.

The resulting classical system, although complex, can be solved relatively quickly.

At the end, we are left with the classical system at its global minimum.

This is used to show the differences between classical and quantum systems.

More generally, it can be applied to any classical system in thermal equilibrium, no matter how complicated.

Cooperation between officials and legislators, integral to classical parliamentary systems, was discouraged.

The model is mainly used as a hypothetical example to illustrate the differences between classical and quantum systems.
