查询词典 genetic

In allusion to the conflict in solving the precision and constringency speed in genetic algorithm, this paper advances a kind of a new genetic algorithm for self adaptation, symmetry and congruity.

Tibetanum were more abundant, which can be used to broaden the genetic basis of common wheat. Cluster analysis exhibited that wild emmer had a closer consanguine relationship to hexaploid wheat, as compared to Aegilops tauschi. In addition, it was found that there was a closer genetic relationship in chloroplast genome of common wheat and T. petropavlavskyi, which indicated that T. petropavlavskyi probably derived from the backcross between common wheat and Polish wheat.

结果］与普通小麦相比，斯卑尔脱小麦和西藏半野生小麦等群体内的叶绿体遗传变异更丰富，可以作为普通小麦新的细胞质遗传变异来源；与粗山羊草相比，野生二粒小麦与六倍体小麦间存在更近的亲缘关系，这与前人关于二粒小麦是六倍体细胞质供体的研究结果相印证；研究还发现，新疆稻麦与普通小麦在叶绿体基因组上具有很近的亲缘关系，为新疆稻麦是由波兰小麦与普通小麦杂交再由普通小麦回交后产生的假说提供了分子水平上的证据。

The heuristic method emploies a genetic algorithm in reducing the redundant attributes of all attributes. Besides taking fitness function as its heuristic function for its selection operation, the genetic algorithm uses the attribute\'s information entropy to construct the heuristic function for its mutate operation, and in this way it markedly elevate the convergence speed of attribute reduction.

启发式方法采用遗传算法进行属性约简，除了存在于选择操作的适应度启发函数外，还在变异操作中以信息熵为基础构造了启发函数；穷举方法基于循环队列自底向上约简，通过剪枝有效地提高了属性约简集的穷举速度。
