PSO

粒子群算法（Particle Swarm Optimization ,PSO）属于进化算法，是通过模拟鸟群捕食行为设计的。从随机解出发，通过迭代寻找最优解，通过适应度来评价解的品质。

所有的粒子具有以下两个属性：速度、位置。

PSO初始化为一群随机粒子（随机解），然后通过迭代找到最优解。在每次迭代中，粒子通过跟踪极值来更新。

一个是粒子本身所找到的最优解—pbest
一个是整个种群目前找到的最优解—全局极值gbest

公式

速度

$V_{i+1} = w * v_i + c_1 * rand_1 * (pbest_i -x_i) + c_2 8 rand_2 * (gbest_i - x_i)$

位置

$x_{i+1} = x_i + v_{i+1}$

w为惯性因子，一般取1
$c_1、c_2$ 为学习因子，一般取2
$rand_1、rand_2$ 为两个（0，1）之间的随机数
$v_i和x_i$ 分别表示粒子第i维的速度和位置
$pbest_i、gbest_i$ 分别表示某个粒子最好位置第i维的值、整个种群最好位置第i维的值

Struts2学习云端月影
最近开始关注struts2的新特性，从这个版本开始，Struts开始使用convention-plugin代替codebehind-plugin来实现struts的零配置。配置文件精简了，的确是简便了开发过程，但是，我们熟悉的配置突然disappear了，真是一下很不适应。跟着潮流走吧，看看该怎样来搞定convention-plugin。使用Convention插件，你需要将其JAR文件放
Java新手入门的30个基本概念二 aijuans java 新手 java 入门
基本概念:　　1.OOP中唯一关系的是对象的接口是什么,就像计算机的销售商她不管电源内部结构是怎样的,他只关系能否给你提供电就行了,也就是只要知道can or not而不是how and why.所有的程序是由一定的属性和行为对象组成的,不同的对象的访问通过函数调用来完成,对象间所有的交流都是通过方法调用,通过对封装对象数据,很大限度上提高复用率。　　2.OOP中最重要的思想是类,类是模板是蓝图,
