摘要

Locating a good initial point for a local iterative optimization method is an important task since they are strongly dependent on it. In this paper, a pre-processing step that exploits time series forecasting is proposed to deal with this problem. The suggested step could work alongside any local method and has the advantage of increasing the percentage of initial points that lead to the global minimizer, as shown by the numerical results. The proposed technique is compared to the corresponding utilized local method for a variety of well-known, as well as randomly generated, test objective functions with promising performance.
