systems with contact. Contact events have high `Lyapunov exponents
<https://en.wikipedia.org/wiki/Lyapunov_exponent>`__; this is a property of any rigid-body simulator (and indeed of
`real-world physics <https://en.wikipedia.org/wiki/Roulette>`__) and is not MuJoCo-specific.
- Exact reproducibillity is only guaranteed within a **single version**. Small numerical differences are quite common
between versioned releases, for example due to code optimizations. This means that when saving an initial state and an
open-loop control sequence, the resulting rolled-out trajectory will be identical within the same version but will
likely be different between MuJoCo versions.
