As a result, it shows thatthe static or dynamic subsystem optimum alone is not equal to the system optimum. Three initial value problems met in the optimal design of flying vehicle are studied andconclusions are derived that: orthogonal test method can be adopted to decide the initial valueof static optimization problem, some mathematical techniques can be used to deal with thecostate variables of Maximum Principle and decide the initial value of the costate variable,the indirect method can be used to get the analytical solution under ideal case to guide thechoice of the initial control curve in the direct method. With some numerical examples oftrajectory optimization, it shows that all these methods are useful not only in accelerating theconvergence but also in converging to the global optimum.

This approach not only inherits the advantages of absolute density based algorithms which can discover arbitrary shape clusters and are insensitive to noises , but also efficiently solves the following common problems: clustering results are very sensitive to the user-deflned parameters, reasonable parameters are hard to be determined, and high density clusters are contained fully in coterminous low density clusters. With this approach, incremental clustering can also be supported effectively by defining the affected sets and seed sets of the updating objects in this approach.
聚类算法的有效性问题主要表现在三个方面:其一,聚类算法大多要求用户输入一定的参数,例如希望产生的簇的数目,而这些参数通常难以确定,特别是针对高维空间中稀疏分布的实际应用数据集,用户几乎无法给出合适的算法参数,因此非专业用户需要与数据分析专家密切配合才能保证获得理想的聚类结果,导致算法的使用极为不便;其二,聚类结果对于输入的参数值过于敏感J,往往参数值的一些轻微变化却产生聚类结果的很大差异;其三,对于高维的实际应用数据集,其数据分布往往是稀疏的、杂乱的,很难为算法选择全局的参数进行准确的聚类分析,使得聚类的质量难以保证。
