查询词典 Boolean

In Chapter 3,we classify a binary-coded individual space equivalently withthe help of the ideals of Boolean algebra and analyze the search capabilitiesof a new kind of algebraic crossover operator in these equivalence classes,thenprovide the algebraic representation of a type of genetic algorithms by usingthe permutation group,therefore we can derive a lot of new forms of geneticalgorithms.

第三章运用Boole代数的理想将二进制编码的个体空间进行等价分类，分析了一类代数杂交算子在这些等价类上的搜索能力；然后利用置换群给出一类遗传算法的代数表示，由此导出多种新形式的遗传算法，并给出其中两类算法形式的收敛性结果。

Finally, PNV had been mapped according to Boolean discrete methods to connect climate submodel and vegetation submodel by GIS. PNV map first represented the spatial distribution of all vegetation types of 4 physiognomic levels in Taiwan, also integrated the diverse comments of altitudinal vegetation zones and geographical climatic regions in the past. Besides, the scattered ranges of 36 dominant trees in the moisture-thermal regime and climatic zone had been drawn via coordinating 585 plot-data with MWI and WDI.

为达绘制潜在植群图之最终目标，本研究以MWI及WDI之网格图层代表气候亚模型，以潜在植群形相分类方案之各阶类型代表植群亚模型，藉由布林分离法联系此2亚模型之关系，建构气候–植群分类模型，并以地理资讯系统绘制出包含群系纲、群系亚纲、群系组、群系之潜在植群图，首次完整呈现台湾各阶植群类型之空间分布，合理说明了山地植群带分化、北部植群下降及西南部冬季乾旱等现象，亦整合过去各种有关垂直性山地植群带状分化与水平性地理气候区划分的复杂意见；另外，本研究将585个样区林木座标标定於MWI及WDI，绘制36种林木於水热境制及热量气候带之分布范围。
