Query Optimization (there is a sub-section for Simulated Annealing in this … WebbSimulated annealing (SA) is a method for solving unconstrained and bound-constrained optimization problems. The method models the physical process of heating a material and then slowly lowering the temperature to decrease defects, thus minimizing the system energy. At each iteration of the simulated annealing algorithm, a new point is randomly ...
WebbSimulated annealing is an algorithm based on the physical annealing process used in metallurgy. During physical annealing, the metal is heated up until it reaches its annealing temperature and then is gradually cooled down to change it into the desired shape.
