我为我的公司在1992年为货运业开发的3D激光表面轮廓系统开发了一个家庭酿造GA。 该系统依赖于三维三角测量，并使用了定制的激光线扫描仪，512x512相机(具有定制的捕获hw)。相机和激光之间的距离永远不会是精确的，相机的焦点也不会在你期望的256,256的位置找到!

尝试使用标准几何和模拟退火式方程求解来计算校准参数是一场噩梦。

遗传算法在一个晚上就完成了，我创建了一个校准立方体来测试它。我知道立方体的精度很高，因此我的想法是，我的遗传算法可以为每个扫描单元进化一组自定义三角测量参数，以克服生产变化。

这招很管用。退一步说，我简直目瞪口呆!在大约10代的时间里，我的“虚拟”立方体(由原始扫描生成并根据校准参数重新创建)实际上看起来像一个立方体!经过大约50代之后，我得到了我需要的校准。

In 2007-9 I developed some software for reading datamatrix patterns. Often these patterns were difficult to read, being indented into scratched surfaces with all kinds of reflectance properties, fuzzy chemically etched markings and so on. I used a GA to fine tune various parameters of the vision algorithms to give the best results on a database of 300 images having known properties. Parameters were things like downsampling resolution, RANSAC parameters, amount of erosion and dilation, low pass filtering radius, and a few others. Running the optimisation over several days this produced results which were about 20% better than naive values on a test set of images unseen during the optimisation phase.

这个系统完全是从零开始编写的，我没有使用任何其他库。我并不反对使用这些东西，只要它们能提供可靠的结果，但是您必须注意许可兼容性和代码可移植性问题。

当你打算粉刷你的房子时，通常很难得到一个确切的颜色组合。通常，你脑海中有一些颜色，但它不是其中一种颜色，供应商向你展示。

昨天，我的GA研究员教授提到了一个发生在德国的真实故事(对不起，我没有更多的参考资料，是的，如果有人要求我可以找到它)。这个家伙(让我们称他为配色员)曾经挨家挨户地帮助人们找到确切的颜色代码(RGB)，这将是客户心目中的衣柜。下面是他的做法:

The color guy used to carry with him a software program which used GA. He used to start with 4 different colors- each coded as a coded Chromosome (whose decoded value would be a RGB value). The consumer picks 1 of the 4 colors (Which is the closest to which he/she has in mind). The program would then assign the maximum fitness to that individual and move onto the next generation using mutation/crossover. The above steps would be repeated till the consumer had found the exact color and then color guy used to tell him the RGB combination!

通过将最大适应度分配给接近消费者想法的颜色，配色员的程序增加了收敛到消费者想法的颜色的机会。我发现它很有趣!

现在我已经得到了一个-1，如果你计划更多的-1，请说明这样做的原因!

There was an competition on codechef.com (great site by the way, monthly programming competitions) where one was supposed to solve an unsolveable sudoku (one should come as close as possible with as few wrong collumns/rows/etc as possible).What I would do, was to first generate a perfect sudoku and then override the fields, that have been given. From this pretty good basis on I used genetic programming to improve my solution.I couldn't think of a deterministic approach in this case, because the sudoku was 300x300 and search would've taken too long.

在工作中，我遇到了这样一个问题:给定M个任务和N个dsp，如何将任务分配给dsp是最好的?“最佳”定义为“最大负载DSP的负载最小化”。有不同类型的任务，不同的任务类型有不同的性能分支，这取决于它们被分配到哪里，所以我将一组工作到dsp的分配编码为“DNA字符串”，然后使用遗传算法来“培育”我所能“培育”的最佳分配字符串。

它运行得相当好(比我之前的方法好得多，之前的方法是评估每个可能的组合……对于非平凡问题的大小，它将需要数年才能完成!)，唯一的问题是无法判断是否已经达到了最优解。你只能决定当前的“最大努力”是否足够好，或者让它运行更长时间，看看它是否可以做得更好。

在大学期间，我们使用NERO(神经网络和遗传算法的结合)来教游戏中的机器人做出智能决策。非常酷。
