March 2008 Web Server Survey

2008年3月的调查显示,全球共有1亿6千2百多万个活跃网站,比上个月增加了450万个。Google、MySpace等社交平台继续增长,但活跃站点数因隐私设置有所下降。轻量级服务器LiteSpeed的增长速度也非常快。
In the March 2008 survey, we received responses from 162,662,052 sites. Growth has continued to rise over the past few months, with this month seeing a gain of four and a half million new sites.

The largest changes this month are once again seen amongst the blogging and social network providers. Google increases its developer share by gaining 842 thousand hostnames; most of which are used for blogspot.com blogs. Although MySpace gained nearly 200 thousand hostnames this month, the total number of active sites fell noticeably after many more users marked their profiles as private.

Apple has recently started hosting sites created with their own iWeb program. iWeb is a template-based web page creation tool, and the latest version is included with Apple's iLife package. The majority — more than 24 thousand — of these iWeb sites are being served from a single IP address, using the new AppleDotMacServer-1B5626 web server.

While Google is the largest developer to gain share this month, the LiteSpeed web server continues to show very rapid growth on the internet — growing by more than a quarter this month — and is now serving 605 thousand websites around the world.

内容概要:本文介绍了一个基于MATLAB实现的无人机三维路径规划项目,采用蚁群算法(ACO)与多层感知机(MLP)相结合的混合模型(ACO-MLP)。该模型通过三维环境离散化建模,利用ACO进行全局路径搜索,并引入MLP对环境特征进行自适应学习与启发因子优化,实现路径的动态调整与多目标优化。项目解决了高维空间建模、动态障碍规避、局部最优陷阱、算法实时性及多目标权衡等关键技术难题,结合并行计算与参数自适应机制,提升了路径规划的智能性、安全性和工程适用性。文中提供了详细的模型架构、核心算法流程及MATLAB代码示例,涵盖空间建模、信息素更新、MLP训练与融合优化等关键步骤。; 适合人群:具备一定MATLAB编程基础,熟悉智能优化算法与神经网络的高校学生、科研人员及从事无人机路径规划相关工作的工程师;适合从事智能无人系统、自动驾驶、机器人导航等领域的研究人员; 使用场景及目标:①应用于复杂三维环境下的无人机路径规划,如城市物流、灾害救援、军事侦察等场景;②实现飞行安全、能耗优化、路径平滑与实时避障等多目标协同优化;③为智能无人系统的自主决策与环境适应能力提供算法支持; 阅读建议:此资源结合理论模型与MATLAB实践,建议读者在理解ACO与MLP基本原理的基础上,结合代码示例进行仿真调试,重点关注ACO-MLP融合机制、多目标优化函数设计及参数自适应策略的实现,以深入掌握混合智能算法在工程中的应用方法。
