ergodic
er·god·ic E5201950 (ûr-gŏd′ĭk)adj. Of or relating to a system or process whose overall statistical properties can be determined by analysis of a sufficiently large sample of the states of one of its constituents or instances averaged over time.
[German Ergode, a set of points in a space with the property that all points will be included in a trajectory with equal frequency given a sufficient large number of trajectories (coined by Ludwig Eduard Boltzmann from Greek ergon, work; see werg- in Indo-European roots + Greek hodos, way, path) + -ic.]
