介绍了遗传算法在水库优化调度中的应用背景及算法的收敛性,讨论了水库优化调度中遗传算法的基本应用步骤以及存在的问题,给出了算法的各种改进方法,并对遗传算法的应用前景进行了展望。

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。

Genetic analysis of the mutants revealed that rice GA-deficient mutations are not transmitted as Mendelian traits to the next generation following self-pollination of F1 heterozygous plants, although GA-insensitive mutations are transmitted normally.

In this context a genetic algorithm was applied to the four-dimension (4-D) variational data assimilation, which provided a kind of new and effective method in the initial field optimization. The theoretical basis and detailed algorithm were introduced in this paper. At the same time, according to the property of the variational problem itself, we designed the rational genetic coding, operators and parameters.

本文将遗传算法应用于四维变分资料同化问题,提供了一种新的较为有效的NWP初始场优化方法,给出了相应的理论依据和详细算法,并结合变分问题本身的特点,设计了合理的遗传编码、遗传操作和遗传参数。

The robust method, which improves the GVF and optimizes search by PGA, is proposed to extract contour veraciously in this section. Due to the information exchange between adjoining points by chromosome crossover, the points are driven to optimization positions in the fined-grained model.

因此,本文通过改进GVF Snakes梯度矢量流,并引入遗传优化搜索,提出了一种稳健的目标提取与跟踪算法:即对于收敛于局部极值处的轮廓控制点,利用细粒度遗传算法,将相邻的处于全局最优控制点的信息通过染色体遗传操作传递给这些点,并驱使它们向全局最优处运动。

An explicit definition of local peak is shown, and the existence condition of local peak is given. It is proved that the GA is constringent at the neighbor of its local peak. The theoretical evidences of some improvements on GA are given, which points out the way forward for improving GAs performance.

关于遗传算法的收敛性研究的一些典型结果包括:文献 [2 ]分析了在种群规模无穷的情况下典型遗传算法的收敛性;文献 [3]证明了典型遗传算法不收敛,而如果对算法采取记录每一代中最佳个体的策略,则改进的算法收敛;文献 [4]提出了一种等价的遗传算法,并给出了收敛条件与收敛速度;文献 [5 ]研

Haplotype is a lineable combination of alleles at multiple loci that are transmitted together on chromosome or mitochondrion.
