For diamonds, annealing had previously been used only to change the mineral's color.
The now commonly employed optimisation methods of simulated annealing and evolutionary algorithms (which include genetic algorithms) possess distinct advantages over the Monte-Carlo [2] and grid search [3-4] methods previously employed, in that they search the relevant parameter space in a much more efficient manner.
They are said to be ideal for low temperature applications, including annealing, preheating, powder or liquid paint curing.
