我构建了一个简单的GA，用于在音乐播放时从频谱中提取有用的模式。输出用于驱动winamp插件中的图形效果。

输入:一些FFT帧(想象一个二维浮点数组) 输出:单个浮点值(输入的加权和)，阈值为0.0或1.0 基因:输入权重 适应度函数:占空比、脉宽、BPM在合理范围内的组合。

我将一些ga调整到频谱的不同部分以及不同的BPM限制，所以它们不会趋向于收敛到相同的模式。来自每个种群的前4个的输出被发送到渲染引擎。

一个有趣的副作用是，整个人群的平均健康状况是音乐变化的一个很好的指标，尽管通常需要4-5秒才能发现。

在我的本科论文中，我使用遗传编程来开发用于空中搜索和救援的合作搜索策略。我使用一个名为NetLogo(基于StarLogo)的开源代理建模平台作为世界模型。NetLogo是用java写的，因此提供了java api -所以GP框架需要基于java -我使用的一个叫做JGAP，还有另一个开源GP框架在java中，我知道叫做ECJ。

模拟运行起来非常慢(我认为这是由于NetLogo模型)，所以我的功能/终端集非常有限，限制了搜索空间。尽管如此，我还是想出了一些很好的解决办法。如果你有这种冲动，你可以在我的论文http://www.cse.unsw.edu.au/~ekjo014/z3157867_Thesis.pdf的第三章读到

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。

进化计算研究生班: 开发了TopCoder马拉松比赛49:megpartty的解决方案。我的小组正在测试不同的域表示法，以及不同的表示法如何影响ga找到正确答案的能力。我们为这个问题编写了自己的代码。

Neuroevolution and Generative and Developmental Systems, Graduate Class: Developed an Othello game board evaluator that was used in the min-max tree of a computer player. The player was set to evaluate one-deep into the game, and trained to play against a greedy computer player that considered corners of vital importance. The training player saw either 3 or 4 deep (I'll need to look at my config files to answer, and they're on a different computer). The goal of the experiment was to compare Novelty Search to traditional, fitness-based search in the Game Board Evaluation domain. Results were relatively inconclusive, unfortunately. While both the novelty search and fitness-based search methods came to a solution (showing that Novelty Search can be used in the Othello domain), it was possible to have a solution to this domain with no hidden nodes. Apparently I didn't create a sufficiently competent trainer if a linear solution was available (and it was possible to have a solution right out of the gates). I believe my implementation of Fitness-based search produced solutions more quickly than my implementation of Novelty search, this time. (this isn't always the case). Either way, I used ANJI, "Another NEAT Java Implementation" for the neural network code, with various modifications. The Othello game I wrote myself.

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.

这是一段时间以前的事了，但我滚动了一个GA来进化实际上是图像处理内核的东西，以从哈勃太空望远镜(HST)图像中去除宇宙射线痕迹。标准的方法是用哈勃望远镜进行多次曝光，只保留所有图像中相同的东西。由于HST时间是如此宝贵，我是一个天文学爱好者，最近参加了进化计算大会，我考虑使用GA来清理单次曝光。

这些个体以树的形式存在，以3x3像素的区域作为输入，执行一些计算，并决定是否以及如何修改中心像素。通过将输出图像与用传统方法(即叠加曝光)清理的图像进行比较来判断适合度。

这实际上是可行的，但还不足以让我们放弃原来的方法。如果我的论文没有时间限制，我可能已经扩展了算法可用的遗传部分。我很确定我可以大大提高它。

使用的库:如果我没记错的话，用于天文图像数据处理和I/O的IRAF和cfitsio。
