A system is said to present annealed disorder when some parameters entering its definition are random variables, but whose evolution is related to that of the degrees of freedom defining the system. It is defined in opposition to quenched disorder, where the random variables may not change its value.
Systems with annealed disorder are usually considered to be easier to deal with mathematically, since the average on the disorder and the thermal average may be treated on the same footing.

Famous quotes containing the word disorder:
“In a town-meeting, the great secret of political science was uncovered, and the problem solved, how to give every individual his fair weight in the government, without any disorder from numbers. In a town-meeting, the roots of society were reached. Here the rich gave counsel, but the poor also; and moreover, the just and the unjust.”
—Ralph Waldo Emerson (1803–1882)
