中国传统武术发展战略探析

武术作为中华民族的瑰宝,不仅具有悠久的历史和深厚的文化底蕴,而且也是在中国传统哲学、古典美学、伦理学、医学等多种学术文化长期熏陶下形成的一项内涵丰富,自成体系的运动项目。正因为如此,它的产生,形成,发展,繁荣所经历的４个不同的阶段,乃是中国武术日臻的统一过程,所以我们继承和发展传统的武术,就必须努力做到：１从中国传统优秀文化的内涵上找到闪光点,增进理论建设,以理论指导实践;２加大武术在体育学科中所

已知工件最大加工时间的两台同类机半在线问题

考虑已知工件最大加工时间的两台同类机半在线问题．机器M1,M2的速度分别为s1=1,s2=s(s≥1),工件是一个一个独立地到来,工件的信息是逐个释放的,但所有工件中加工时间为最大的工件的加工时间是已知的,目标函数为极小化最大机器负载．此模型简记为Q2／known largest job／Cmax．作者给出了Qmax2算法并证明此算法的竞争比为2(s 1)/s 2(1≤s≤2)和(s 1)/s(s>2),且是紧的．同时给出Q2／known largest job／Cmax问题的一个下界,并且证明Qmax2算法的竞争比与最优算法竞争比之差不大于1/4.     

Shuffled complex evolution approach for effective and efficient global minimization

The degree of difficulty in solving a global optimization problem is in general dependent on the dimensionality of the problem and certain characteristics of the objective function. This paper discusses five of these characteristics and presents a strategy for function optimization called the shuffled complex evolution (SCE) method, which promises to be robust, effective, and efficient for a broad class of problems. The SCE method is based on a synthesis of four concepts that have proved successful for global optimization: (a) combination of probabilistic and deterministic approaches; (b) clustering; (c) systematic evolution of a complex of points spanning the space, in the direction of global improvement; and (d) competitive evolution. Two algorithms based on the SCE method are presented. These algorithms are tested by running 100 randomly initiated trials on eight test problems of differing difficulty. The performance of the two algorithms is compared to that of the controlled random search CRS2 method presented by Price (1983, 1987) and to a multistart algorithm based on the simplex method presented by Nelder and Mead (1965).This work was partially funded by the National Science Foundation, Grant ECE-86-10584, and by the National Weather Service, Grant NA85AA-H-HY088.     

Rapid Determination of Cellulose and Hemicellulose Contents in Corn Stover Using Near-Infrared Spectroscopy Combined with Wavelength Selection

The contents of cellulose and hemicellulose (C and H) in corn stover (CS) have an important influence on its biochemical transformation and utilization. To rapidly detect the C and H contents in CS by near-infrared spectroscopy (NIRS), the characteristic wavelength selection algorithms of backward partial least squares (BIPLS), competitive adaptive reweighted sampling (CARS), BIPLS combined with CARS, BIPLS combined with a genetic simulated annealing algorithm (GSA), and CARS combined with a GSA were used to select the wavelength variables (WVs) for C and H, and the corresponding regression correction models were established. The results showed that five wavelength selection algorithms could effectively eliminate irrelevant redundant WVs, and their modeling performance was significantly superior to that of the full spectrum. Through comparison and analysis, it was found that CARS combined with GSA had the best comprehensive performance; the predictive root mean squared errors of the C and H regression model were 0.786% and 0.893%, and the residual predictive deviations were 3.815 and 12.435, respectively. The wavelength selection algorithm could effectively improve the accuracy of the quantitative analysis of C and H contents in CS by NIRS, providing theoretical support for the research and development of related online detection equipment.
