R 树, 存取方式的当中最普遍的的用长方形, 是根据区域的启发式优化围绕的长方形在各个内在结点通过运行在一张规范化的试验平台下高度变化的数据, 询问和操作众多的实验, 我们能设计合并联合的优化的R* 树区域, 各个附寄的长方形边际和交叠在目录使用我们规范化的试验床在详尽表现比较,它结果R* 树清楚地胜过现有的R 树变形Guttman’s线性和二次方R 树和R 树的格林变形,R* 树的这优势举行为不同的型询问和操作, 譬如地图覆盖物。 为两个长方形和多维点在所有实验从一个实用观点R* 树是非常有吸

本文给出了一种利用幅相加权对阵列天线进行全局优化的方法。为了使天线的辐射波束形成给定的
方向图,采用联合应用DFP和BFGS公式的变度量算法对阵列天线各单元的馈电幅度和相位分布进行优化,
通过C++语言编程计算实现,从而使得优化后的阵列天线主波束形状能够与预给波束形状相吻合,达到设计
要求。全局优化是本文的特色,它弥补了局部优化结果的精确度依赖于初始值的缺点,因而得以保证通过优
化得到的天线主波束与给定波束的主瓣相吻合,副瓣也得到有效控制。该方法具有快速收敛,计算量小等优

During the past two decades, a variety of
multiobjective evolutionary algorithms (MOEAs) have been
proposed in the literature. As pointed out in some recent studies,
however, the performance of an MOEA can strongly depend on
the Pareto front shap
