The key points of DGA is to start evolution with initial population evenly distributed in searching space to avoid the leakiness of subspace, to accelerate the searching process by directed crossover and mutation, to improve holistic survival and adaptive ability by means of competition and parallel evolution in genetic system. However, the crossover and mutation act on different lays in space made the searching uniform.

其基本思路是以空间上均匀分布的初始点展开演化以避免子空间的遗漏，以有方向性的杂交和变异加速和调节搜索，同时杂交和变异作用在不同层面上使搜索在整体上均匀化，通过遗传系统里的并行竞争提高整个群体的生存适应力，从而达到整体优化的目的。

In this paper, we propose an improved evolutionary programming using a mixed strategy based on Gaussion mutation and single-point mutation, which is named SPCEP.

This mixed strategy has been tested on benchmark functions. The simulation results show that the mixed mutation strategy is superior to any pure mutation strategy.

使用国际通用标准函数来测试这种新算法，仿真的结果表明了基于物种保护的混合变异算子进化策略优于任何一种纯策略的进化策略。

Tracing the development process (i.e. the life history) of vacuum cleaner, we found similarities between product development and evolution trend, such as the theory of "evolve by use and degenerate by no-use" by Lamarck, the theories of mutation, excessive breeding, competition for existence, and survival of the fittest in the Theory of Natural Selection by Darwin and Wallace, as well as the theory of mutation in Neo-Darwinism.

文中经由观察吸尘器诞生后的发展过程，亦即它所经历的生命史中，归纳出它所显现的演变现象有些似乎和演化论有相似之处，例如：Lamarck的用进废退演化现象，Darwin天择说中的变异、过度繁殖、生存竞争、适者生存等，及集合各家说法的Neo-Darwinism中的突变等。

Results In the 10 members, T→C nucleotide change at the 223 base of exon 3 was detected in 9, including 6 with Best disease who was confirmed by ophthalmoscopy and electrophysiological examination in whom 2 were affirmed as having homozygote of this mutation. Other 3 young family members with VMD2 gene mutation only had abnormal electro-oculogram manifestations.

结果Best病家系10个成员中，9人VMD2基因外显子2第223位碱基C-T颠换，其中6人通过眼底和眼电生理检查证实为Best病患者，2人为该突变的纯合子；另外有3个年轻成员虽然携带VMD2基因突变，临床上仅表现为眼电图的异常。

Structural matter drops to hit water with fixed rate phut from certain height, inchoate and main the structure that attacks water process in the light of phut is answered begin research, and press mutation of field of force and Xing Bo to wait to study however to entering the underwater after water less, and add with each passing day as large bridge and marine project much, the construction in these projects and the phenomenon that phut of large construction content also appeared to hit water in use process, like Guangdong 9 rivers big bridge is bumped to break down after collapsing, large area bridge floor falls into surface to wait, the meeting such as mutation of field of pressure of the underwater after this kind of phut hits water and Xing Bo is right all round structural products gives birth to certain influence, evaluate this kind of influence to have real project sense to construction and design.

结构物从一定高度落下以一定速度砰击水面，早期主要针对砰击入水过程的结构响应开展探究，而对入水后水下压力场突变和兴波等却探究较少，而随着大型桥梁和海洋工程日渐增多，在这些工程的施工和使用过程中也出现了大型结构物砰击入水的现象，如广东九江大桥被撞垮塌后大面积桥面落入水面等，这种砰击入水后水下压力场突变和兴波等会对四周结构物产生一定影响，评价这种影响对施工和设计具有现实的工程意义。

Then it compares these operators' performance through its convergence quality,and it demonstrates that this over-flow dealing method is effective through a group of experiments,the mutation operators used in single-objective optimization have the respectable distribution to polynomial mutation and achieve better convergence quality.
