ergodicity

9.9

A property of a system whose long-term behaviour does not depend on its starting state and settles into one pattern

noun
/ˌɜrɡəˈdɪsɪti/

Specialized

: ergodicidad

By applying the concept of ergodicity, scientists can predict the long-term behavior of stochastic processes without considering their initial states.

Examples

This similarity would imply that the effects of space and time on diversity are interchangeable, and thus recalls the property of ergodicity in mathematics.

Academic text (2010)
OK, that's that's another way of looking at what ergodicity means.
In studying complex systems, researchers often explore the principle of ergodicity to understand how past events do not affect the long-term outcome.
The theory of ergodicity suggests that, regardless of where a particle starts, its distribution will stabilize over time.

ergodicity singular

ergodicities plural

Morphology

ergodicity = ergodic (transparent) = ergodic + ity

Standard nominalization of the adjective 'ergodic' with '-ity'; a learner who knows 'ergodic' can infer the noun denotes the state or property.

Etymology

Ergodicity comes from Greek roots ergon 'work' and hodos 'path'. A helpful way to remember it is 'work along a path': in an ergodic system every path over time shows the same behaviour, so the long-term result does not depend on the starting point.
