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.
   1. The process used to render glass, iron, etc., less
      brittle, performed by allowing them to cool very gradually
      from a high heat.
      [1913 Webster]

   2. The burning of metallic colors into glass, earthenware,
      etc.

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.
