遗传算法(GA)和遗传规划(GP)是一个有趣的研究领域。
我想知道你使用GA/GP解决的具体问题，以及如果你没有自己的库/框架，你使用了什么库/框架。
问题:
你用GA/GP解决过什么问题? 你使用了哪些库/框架?
我在寻找第一手的经验，所以请不要回答，除非你有。

没有家庭作业。
1995年，我作为专业程序员的第一份工作是为标准普尔500指数期货编写一个基于遗传算法的自动交易系统。该应用程序是用Visual Basic 3 [!我不知道我当时是怎么做的，因为VB3甚至没有课程。
The application started with a population of randomly-generated fixed-length strings (the "gene" part), each of which corresponded to a specific shape in the minute-by-minute price data of the S&P500 futures, as well as a specific order (buy or sell) and stop-loss and stop-profit amounts. Each string (or "gene") had its profit performance evaluated by a run through 3 years of historical data; whenever the specified "shape" matched the historical data, I assumed the corresponding buy or sell order and evaluated the trade's result. I added the caveat that each gene started with a fixed amount of money and could thus potentially go broke and be removed from the gene pool entirely.
在对种群的每一次评估之后，幸存者被随机杂交(通过混合来自两个亲本的片段)，一个基因被选择为亲本的可能性与它产生的利润成正比。我还添加了点突变的可能性，让事情变得有趣一点。经过几百代这样的基因，我最终得到了一个基因群，它可以把5000美元变成平均约10000美元，而且没有死亡/破碎的可能性(当然是在历史数据上)。
Unfortunately, I never got the chance to use this system live, since my boss lost close to $100,000 in less than 3 months trading the traditional way, and he lost his willingness to continue with the project. In retrospect, I think the system would have made huge profits - not because I was necessarily doing anything right, but because the population of genes that I produced happened to be biased towards buy orders (as opposed to sell orders) by about a 5:1 ratio. And as we know with our 20/20 hindsight, the market went up a bit after 1995.

在学校的一次研讨会上，我们开发了一个基于音乐模式生成音乐的应用程序。该程序是在Java中构建的，输出是一个midi文件与歌曲。我们使用不同的GA方法来生成音乐。我认为这个程序可以用来探索新的组合。
我是一个研究使用进化计算(EC)来自动修复现有程序中的错误的团队的成员。我们已经在现实世界的软件项目中成功地修复了一些真实的错误(参见本项目的主页)。
这种EC修复技术有两种应用。
The first (code and reproduction information available through the project page) evolves the abstract syntax trees parsed from existing C programs and is implemented in Ocaml using our own custom EC engine. The second (code and reproduction information available through the project page), my personal contribution to the project, evolves the x86 assembly or Java byte code compiled from programs written in a number of programming languages. This application is implemented in Clojure and also uses its own custom built EC engine.
进化计算的一个优点是技术的简单性，使得编写自己的自定义实现不太困难。有关遗传规划的一个很好的免费的介绍性文本，请参阅遗传规划的现场指南。
我不知道家庭作业算不算…
在我学习期间，我们推出了自己的程序来解决旅行推销员问题。
我们的想法是对几个标准进行比较(映射问题的难度，性能等)，我们还使用了其他技术，如模拟退火。
它运行得很好，但我们花了一段时间来理解如何正确地进行“复制”阶段:将手头的问题建模成适合遗传编程的东西，这对我来说是最难的部分……
这是一门有趣的课程，因为我们也涉猎了神经网络之类的知识。
我想知道是否有人在“生产”代码中使用这种编程。
我和一个同事正在研究一种解决方案，使用我们公司要求的各种标准将货物装载到卡车上。我一直在研究遗传算法的解决方案，而他正在使用具有激进修剪的分支和绑定。我们仍在实施这个解决方案的过程中，但到目前为止，我们已经取得了良好的结果。
