Simulated annealing (SA) algorithm is a popular intelligent optimization algorithm which has been successfully applied in many fields. Parameters’ setting is a key factor for its performance, but it is also a tedious work. To simplify parameters setting, we present a list-based simulated annealing (LBSA) algorithm to solve traveling salesman problem (TSP). LBSA algorithm uses a novel simulated annealing with adaptive cooling ratesthe Implementation of a simulated annealing algorithm for Matlab In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, Combined Simulated Annealing Algorithm for the Discrete simulated annealing with adaptive cooling ratesthe The combined simulated annealing (CSA) algorithm was developed for the discrete facility location problem (DFLP) in the paper. The method is a two-layer algorithm, in which the external subalgorithm optimizes the decision of the facility location decision while the internal subalgorithm optimizes the decision of the allocation of customer's demand under the determined location decision.
The best results were obtained using simulated annealing with adaptive cooling and reheating as a function of cost, and a rule-based preprocessor. This approach enabled us to obtain valid schedules for the timetabling problem for a large university, using a complex cost function that includes student preferences.

In this study, we propose a hybrid algorithm based on the concepts borrowed from tabu search (TS) and simulated annealing (SA) to solve the ccTP. This algorithm, called ATSA (adaptive tabu-simulated annealing), is an SA approach supplemented with a tabu list and adaptive cooling strategy.

Such a schedule is called an adaptive cooling schedule (Ingber, 1989; Azizi and Zolfaghari, 2004). An adaptive cooling schedule tries to keep the annealing temperature close to the equilibrium as well as reducing the number of transitions to reach equilibrium. It adjusts the rate of temperature decrease based on the past history of the run. A comparison of several cooling schedules for simulated simulated annealing with adaptive cooling ratesthe A study of several cooling schedules for the simulated annealing optimization algorithm, as applied to a residual statics problem in seismic data processing, is undertaken and discussed. A variety of schedules which depend on usercontrolled parameters and an adaptive annealing schedule which depends on the system itself are considered. simulatedAnnealing: An adaptation of the simulated annealing simulated annealing with adaptive cooling ratesthe Simulated annealing mimics the physical process of annealing metals together. Kirkpatrick et al. (1983) introduces this analogy and demonstrates its use; the implementation here follows this demonstration closely, with some modifications to make it better suited for psychometric models.
For instance, Adaptive Simulated Annealing, also known as the very fast simulated reannealing, is a very efficient version of simulated annealing.
