Properties

Insensitive to differences in environmental input.

Rapid dissipation of information from environment―hence no dynamic memory.

Exponential divergence of orbits or responses with small differences in environmental input.

Rapid dissipation of information from environment―no dynamic memory.

Long-range or power-law correlation.

Motion has no exponential dissipation, hence long memory.

Sensitive and therefore responsive to inputs from the environment.

Most compatible with biological computation and control.
