详细表述了分数阶傅立叶变换的离散实现,将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the
fractional Fourier transform that are freely available and we describe our own implementation that lters
the best out of the existing ones. Two types of transforms are considered: First the fast approximate
fractional Fourier transform algorithm for which two algorithms are available. The method is described
in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform.
IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by
A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier
transform algorithm described in the master thesis C . Candan. The discrete fractional Fourier transform,
Bilkent Univ., 1998 and an algorithm described by S.C. Pei, M.H. Yeh, and C.C Tseng: Digital fractional

自适应差分进化
最近一段时间优化方法,尤其是进化计算技术,属于主要讨论的话题。遗传算法中,相对较新的方法,在这一领域 (他们的发展已经开始十或十五年前),越来越会变得越来越流行的工具,为解决日益谱的优化任务,已知的一些实际应用。我们已开始处理这些方法,2000 年夏天。有人能帮助我们解决当今来到焦点的优化问题相对不同套的同样可靠的、 有效的和通用算法需要。除其他外一直在调查以下几个问题: 鉴别材料模型参数、 回归分析、 可以用来从实验 resultstopological optimizationssome 工程任务,例如,钢筋混凝土梁与其他结构和结构构件的优化近似的材料模型参数估计的神经网络的训练。
