Now more and more feel search engine optimizes what cannot say to be a technology, however a kind of strategy, a kind of standard, the standard that a website observes stopped, we are studying these standards, these normative constitutor are business of search engine service, be being abided by is a website, and carrying out these normative ability is SEO.

现在越来越感觉到搜索引擎优化不能称之为技术，而是一种策略，一种规范，一个网站遵守的规范罢了，我们都在研究这些规范，这些规范的制定者是搜索引擎服务商，遵守着是网站，而执行这些规范才是SEO。

Among them 3 kinds of pattern are more familiar, it is mode of forum public relations, the small number of people gives out gigantic voice through occupying the platform such as forum, BBS by force, flooded popular true sound; 2 it is the network shoves a hand, prove through plan and lack but the operation with apparent directivity, the purpose; that achieves attack competitor or information to distribute searchs engine the 3rd kind namely, the search engine that holds market dominant position often screen inimical or the website that does not pay, put the content that with oneself interest positive closes in search result front row, one when intervene the practice that searchs a result made industry goes regular.

其中三种模式比较常见，一是论坛公关模式，少数人通过霸占论坛、BBS等平台发出巨大的声音，淹没了大众的真正声音；二是网络推手，通过策划以及缺乏论证但是指向性明显的操作，达到攻击竞争对手或信息散布的目的；第三种就是搜索引擎，占据市场优势的搜索引擎往往屏蔽不友善或不付钱的网站，并将与自己利益正相关的内容放在搜索结果前列，干预搜索结果的做法成为了业界的一条潜规则。

PSO is a population-based optimization algorithm, which mimics the social behavior of animals in a flock. It makes use of individual and group memory to update each particle position allowing global and local search optimization. The objective function considered was the total weight of the structure subjected to stresses, displacements and forces constraints. The effects of the parameters were investigated as well and such combination of tuning parameters promote a better global search behavior avoiding premature convergence while rapidly converging to the optimal solution. Results showed the effectiveness of the proposed method by comparing with ANSYS Design Optimization Tool (zero-order method). The PSO with the tuning parameters makes it an ideal method for offshore wind turbines foundations optimization tasks.(2) A reliability analysis method for pile foundation bearing axial loads based PSOThe performance function of pile foundation's axially bearing capacity sometimes is nonlinear and complex, on the basis of geometric meaning of structural reliability index, an optimum model with PSO for structural reliability analysis under arbitrary random variables was established, The PSO algorithm is very efficient to solve global optimization problemsIts use in structural reliability field presents not only the advantage of its facility of implementation, but also the possibility to obtain the design point and the failure probability with a good accuracy. In addition, PSO is a zero order algorithm, for no derivative is necessary for its implementation.

本文的研究针对桩式海上风机基础结构的特点，在国内外有关研究成果的基础上对海上风机基础结构优化设计理论和可靠度方法一些相关问题进行了较为深入的研究，具体做了以下几个方面的工作：(1)基于粒子群优化的桩式海上风机基础确定性优化设计方法桩式海上风机基础的优化设计是一个复杂的、非线性约束的优化问题，针对传统的基于梯度信息的优化方法在处理非线性问题中易陷入局部最优解的问题，本文将一种耦合惩罚函数的PSO算法引入到海上风机基础结构概念设计中，PSO算法是从群体动物聚集觅食这一活动中受到启发而发展的，该算法利用个体和群体的信息共享不断改进自身的位置从而进行局部和全局最优搜索，本文中以桩和三脚架连接段直径及壁厚为设计变量，以基础总重量作为优化的目标函数，在给定的约束条件下建立了三脚架基础优化数学模型，另外本文还研究了PSO参数变化对结果的影响，协调的参数组合可以避免陷入早熟收敛而能够快速的获得全局的最优解，通过与ANSYS优化模块的计算结果比较验证了该方法的有效性，本方法为海上风机基础的确定性设计提供了一条有效的途径。
