摘要
全局优化方法——三角旋回算法(TriangleGyrationAlgorithm,TGA),具有结构简单、鲁棒性强和快速收敛的特点。算法的寻优过程采用历史最优目标函数值进行指导,利用三角变换进行迭代使其能够快速收敛到全局最优。用一个典型的算例对三角旋回算法进行了性能分析,并且将该算法应用在水库中长期优化调度中。与其他几种常见算法的比较结果表明,该算法综合性能优越,在优化方法领域具有广阔的应用前景。
A new global optimization method, which is named Triangle Gyration Algorithm (TGA). It embodies the characteristics of simple structure, good robust and fast convergence. The individual of algorithm in every generation is guided by the best objective function value and transformed by the trigonometric function, which ensure the whole progress could converge at the global optimal points soon. Compare to the usual optimization methods with a numerical example and longterm scheduling of hydro plant, TGA manifests the best performance and has wide application outlook.
