最强大的王爽汇编语言学习环境
这是采用VMwere Workstation 12 pro虚拟机软件,搭建的MS-DOS学习环境,在windowsXP/8/10及linux中均可以使用,在这个环境中,我集成了CCDOS中文系统,pdos中文系统,使用这些系统,可以进行中文输入与显示。还集成了,十分著名的汇编语言调试工具TR,它比debug更加强大。并且集成了适合王爽汇编语言学习的微软汇编语言编译器masm5和dos中最强大的文本编辑器 vim73 for DOS,这是一个支持彩色文本格式显示的汇编代码最佳工具,除此我还虚拟了一张1.44M的软盘,方便学习书中软盘操作实验,并且增加了长文件名称处理工具组合longdos等,在这

C++ 实现的HTTP协议打包解析器
这个库不依赖别的库,不需要捆绑庞大的网络框架,它就实现一个朴素的需求:对http报文进行解析和打包。公司是一家上市网络公司,这个小库使用了2年了,还是比较好用。有问题或者改进意见可以联系我。

遗传算法优化神经网络的拓扑结构与权值
【实例简介】遗传算法(GA)和人工神经网络(ANN)的相互结合有辅助式和合作式两种方式.本文在此基础上提出了融合、BP_GA和GA_BP三种算法,并采用GA_BP算法同时优化BP神经网络的结构、权值和阈值,研究和实现了一套先进的编码技术和进化策略,克服了传统BP神经网络经验尝试方法的盲目性.实例优化与检验结果表明:遗传算法优化获得的神经网络比由经验尝试法得到的BP网络性能更优异,方法更合理.

最大效用频谱分配算法
关于认知无线电频谱分配方面的知识,希望对寻找资源的同学有帮助第37卷第19期何利,郑湘渝,刘振坤:基于图着色理论的最大效用频谱分配算法9542最大平均效用ISAA,但小于CSGC的时问开销。但是由图2可知,在同一图2分别给出了CSGC、ISAA和MUAA3种算法在用频谱数目下,MUAA算法的最大平均效用是最高的,并且随户取值为7和12时的最大平均效用。随着系统中频谱数的不着系统中频谱数目的増多,MUAA算法的最大平均效用高于淅增加,3种算法的最大平均效用基本呈现上升趋势,但是SAA算法,ISAA算法和(S(C算法的效用相同。MUAA算MUAA算法的最大平均效用増加趋势大于CSGC和ISAA算法以牺牲较少的时间开销获得了较大的系统效用,可见,法,这是因为随着频谱数目增加,MUAA算法的用户提高了MUAA算法是这3种算法中最优的。频谱的复用率。5结束语120本文研究了认知无线电网络屮基于图论着色模型的频谱H-ISAAMUAA分配算法,在分析CSGC、ISAA存在的问题基础上,提出兼CSGC顾系统效用和时间开销的MUAA算法,并对3种算法在系统效用和时间开销方面进行仿真比较。仿真结果表明,MUAA算法是有效的。下一步工作是将ISAA的并行计算方法应用2个到MUAA屮,在不增加时间开销的基础上,提高频谱分配的系统效用。参考文献[1] Shared Spectrum Company.

Hence, the differences havemainly been obstructed for robotic developers as well as robotics experts to join robotdevelopmentTo solve the problem, the demand of making common platforms has been increased, andsome platforms have been published Within a common platform, developers can combinevarious software published by other developers, and speed up development by reusing themTherefore, it is expected that developers can more focus on fields of interestROS (Robot Operating System) is a framework for robotic software development. It wasdeveloped by Willow Garage in U.S. OSFR (Open Source Robotics Foundation) has currentlymaintained it.
