Lateral computing of magnitude better than conventional computers. The Simulated annealing algorithm is designed by looking at how the pure crystals form from a heated gaseous state while the system is cooled slowly. The computing problem is redesigned as a simulated annealing exercise and the solutions are arrived at. The working principle of simulated annealing is borrowed from metallurgy: a piece of metal is heated (the atoms are given thermal agitation), and then the metal is left to cool slowly. The slow and regular cooling of the metal allows the atoms to slide progressively their most stable ("minimal energy") positions. (Rapid cooling
Spin glass as the sample is cooled to the transition temperature, magnetization of the sample increases as described by the Curie law. Upon reaching "T", the sample becomes a spin glass and further cooling results in little change in magnetization. This is referred to as the "field-cooled" magnetization. When the external magnetic field is removed, the magnetization of the spin glass falls rapidly to a lower value known as the "remanent" magnetization. Magnetization then decays slowly as it approaches zero (or some small fraction of the original value—this remains unknown). This decay is non-exponential and no simple function can fit the curve
