问题 i'm trying to solve the problem of crossover in genetic algorithm on my permutations. Let's say I have two permutations of 20 integers. I want to crossover them to get two children. Parents have the same integers inside, but the order is different. Example: Parent1: 5 12 60 50 42 21 530 999 112 234 15 152 601 750 442 221 30 969 113 134 Parent2: 12 750 42 113 530 112 5 23415 60 152 601 999 442 221 50 30 969 134 21 Let it be that way - how can I get children of these two? 回答1: What you are

问题 I am having trouble implementing a uniform crossover in java. This is the algorithm; // Uniform Crossover public void UniformCrossover(Individual indi) { if (RVGA.rand.nextDouble() < pc) { // Put your implementation of uniform crossover here // For each gene create a random number in [0, 1]. // If the number is less than 0.5, swap the gene values in // the parents for this gene; other wise, no swapping . } I know I can int tmp and store random number, then if tmp < 0.5 continue with loop I

问题 E.g. I have two random representatives 1 6 8 9 0 3 4 7 5 and 3 6 5 7 8 5 What are the ways to crossover them? Add some empty numbers (or operations or sth) on the end of every genotype so they will have the same size? 3 6 5 7 8 5 -1 -1 -1 where -1 means nothing? Or copy few number from first genotype and some from second? What is the way you use? 回答1: If you already have variable length chromosomes, then it shouldnt matter how you do it, you just need to select a crossover point for each of

For example using your chromosomes, I have selected two points (.) at

How should I perform the crossover operation over my genomes? Where can I find implementations of my problem in C#? 回答1: You should check "Genetic Algorithm Solution of the TSP Avoiding Special Crossover and Mutation" by Gokturk Ucoluk. PDF here . It gives an overview of the special crossover operators for permutations and proposes a clever representation of permutations that works well with

Windows下用惯了PLSQL Developer,切到Mac下总是找不到满意的数据库客户端工具。 使用CrossOver 16+PLSQL Developer 11,安装CrossOver 17+PLSQL Developer 12,运行时会报dll错误。 1.先安装CrossOver 2.再建立Windows容器 3.选择安装PLSQL Developer 4.将Oracle客户端Copy到CrossOver里的C盘 5.运行regedit命令,在\HKEY_CURRENT_USER\Enviornment\增加环境变量 ORACLE_HOME=C:\Soft\Oracle\instantclient_11_2 NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK NLS_DATE_FORMART=yyyy-mm-dd hh24:mi:ss 6.完成 来源: https://www.cnblogs.com/vanuan/p/9575910.html

CrossOver的Linux的回顾

约四个月了,我一直使用的是Ubuntu Linux操作系统上都我的台式机和笔记本电脑的完整时间。这个经历几个星期,我写了一篇文章分享我的发现有关Windows到Linux的迁移过程中的一些。在这篇文章中,我处理的主要概念之一是寻找基于Linux的替代当前的Windows软件的概念。不过,我还报道了事实,即有一些软件应用程序,根本没有值得选择,基于这个原因,建议Linux新手进入葡萄酒包在Linux上运行W indows的软件产品外观。然而,无可否认,葡萄酒是最好的一个粗略位(由评论员说)。 当我第一次开始使用Linux,我听说了CodeWeavers的CrossOver的软件包,致力于在Linux环境中运行Windows应用程序。但是,我不能购买的理由,因为在我眼里它(零售价格为40美元起),它没有提供任何价值。毕竟,这是基于Wine项目,我看到了毫无意义的东西,只是购买的东西重新命名版本,是免费提供。最近,虽然,一些人已经告诉我的CrossOver的奇迹以及它是如何比以前的品牌酒包装,我认为它更。出于这个原因,我决定冒险尝试和购买的CrossOver Linux的标准,以便在Linux上运行几个Windows应用程序。 软件开发 当安装预编译包,我很感兴趣的瓶子概念,是在交叉就业。你看,为了最大限度地孤立可比性和不稳定性,交叉允许您创建具有独立设置个性化的葡萄酒瓶。例如
