| Annotation | The paper considers the problem of finding the global minimum of a multiextremal function. To solve this problem, the simulation annealing algorithm was used. To speed up the process of finding the minimum, the approximation of the objective function by a neural network is applied. The results of algorithm that combines the simulation annealing algorithm using a neural network to approximate objective function and the Nelder-Meade method to refine the solution of the optimization problem are presented. The paper presentS the results of the experiments carried out with a series of multiextremal test problems. The results show a reduction in the number of calculations of the objective function while maintaining high search accuracy. |
