In this implementation, the evolutionary algorithm is hybridized with the simulated annealing algorithm and the hill climbing heuristic. The main aspects are as follows. The Metropolis criterion of the simulated annealing algorithm is introduced to select the offspring in order to make the algorithm more effective to escape the local optimum. In terms of the hill climbing heuristic, the local normal perturbing mutation operator based probability selecting is developed to enhance the local searching of the algorithm.

其主要工作是将进化算法与模拟退火算法及爬山方法相组合，引入模拟退火算法中Metropolis接受准则选择子代，提高算法跳出局部最优解的能力：借鉴爬山方法思想，构造了基于概率选择的局部正态摄动变异算子，以强化进化算法局部细搜索能力；同时进化算法以多种群方式实现，在降低计算时间的同时提高算法收敛到全局最优解的概率。

There is some evidence that this process can be selective (7). A second possibility simply involves a relative selective advantage to wildtype mtDNAs during the expansion of mitochondria that occurs in oogenesis.

The steps of Reduced Gradient optimal method is used on solving the Least Squares theory model. At some situation, some nodes pressure and supply of all water-supply sources are measured in Xi'ning (resistance parameter of all pipes are known). By using the pressure of the experiment and optimal measure points, the state simulation is done respectively to get all nodes' pressure.

利用简约梯度优化法求解给水管网状态估计的最小二乘数学模型，实测某一工况下西宁市配水管网部分节点水压H_0、各水源供水量分别用优化选择的测压点水压和按经验选择的测压点水压估计所有节点的水压，对西宁市配水管网进行了状态估计。

Cluster sampling: When the basic sampling unit in the population is to be found in groups or cluster s the sampling is sometimes carried out by selecting a sample of cluster s and observing all the members of each selected cluster .

整群抽样：一种抽样方法。当母体中的基本抽样单位是按群、组分类时，有时抽样方式是选择一类样本群组，然后对被选择的群组中的每一个样本单位的全体成员进行观察。
