It is a memory less algorithm, as the algorithm does not use any information gathered during the search. 2.Decrease carefully the temperature of the molten metal, until the particles arrange themselves in the ground state of the solid. The Simulated Annealing (SA) algorithm is one of many random optimization algorithms. A. Rana, A.E. In the Artificial Intelligence domain, it refers to a similar process in which the temperature is reduced slowly of a variable that eventually leads to the arrival of greedy descent as the temperature comes closer to zero.
