WebExhaustively searching such access plan spaces is unacceptable. We propose a query optimization algorithm based on simulated annealing, which is a probabilistic hill climbing algorithm. We show the specific formulation of the algorithm for the case of optimizing complex non-recursive queries that arise in the study of linear recursion. WebDetails. Simulated annealing is a global optimization method. For model tuning, it can be used to iteratively search the parameter space for optimal tuning parameter combinations. At each iteration, a new parameter combination is created by perturbing the current parameters in some small way so that they are within a small neighborhood. inf1220 tp 3WebSimulated annealing ( SA) is a probabilistic technique for approximating the global optimum of a given function. Specifically, it is a metaheuristic to approximate global optimization in a large search space for an optimization problem. It is often used when the search space is discrete (e.g., the traveling salesman problem). inf 1234/2012
