Anneal \An*neal"\, v. t. [imp. & p. p. Annealed; p. pr. & vb.
n. Annealing.] [OE. anelen to heat, burn, AS. an?lan; an on
+ ?lan to burn; also OE. anelen to enamel, prob. influenced
by OF. neeler, nieler, to put a black enamel on gold or
silver, F. nieller, fr. LL. nigellare to blacken, fr. L.
nigellus blackish, dim. of niger black. Cf. Niello,
Negro.]
1. To subject to great heat, and then cool slowly, as glass,
cast iron, steel, or other metal, for the purpose of
rendering it less brittle; to temper; to toughen.
[1913 Webster]
2. To heat, as glass, tiles, or earthenware, in order to fix
the colors laid on them.

Annealing \An*neal"ing\, n.

simulated annealing
annealing
A technique which can be applied to any minimisation or
learning process based on successive update steps (either
random or deterministic) where the update step length is
proportional to an arbitrarily set parameter which can play
the role of a temperature. Then, in analogy with the
annealing of metals, the temperature is made high in the early
stages of the process for faster minimisation or learning,
then is reduced for greater stability.
