几周前，我提出了一个关于SO的解决方案，使用遗传算法来解决图布局的问题。这是一个约束优化问题的例子。

同样在机器学习领域，我用c/c++从头开始实现了一个基于ga的分类规则框架。 我还在一个示例项目中使用了GA来训练人工神经网络(ANN)，而不是使用著名的反向传播算法。

此外，作为我研究生研究的一部分，我已经使用GA来训练隐马尔可夫模型，作为基于em的Baum-Welch算法的额外方法(还是在c/c++中)。

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.

我几周前做了这个有趣的小玩意。它生成有趣的互联网图像使用GA。有点傻，但很好笑。

对此有一些见解。它是一些mysql表。一个用于图像列表及其评分(即适合度)，另一个用于子图像及其在页面上的位置。

子图像可以有几个细节，但不是全部实现:+大小，倾斜，旋转，+位置，+image_url。

当人们投票决定这张照片有多有趣时，它或多或少会流传到下一代。如果它存活下来，它会产生5-10个带有轻微突变的后代。目前还没有交叉。

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!
