Several years ago I used ga's to optimize asr (automatic speech recognition) grammars for better recognition rates. I started with fairly simple lists of choices (where the ga was testing combinations of possible terms for each slot) and worked my way up to more open and complex grammars. Fitness was determined by measuring separation between terms/sequences under a kind of phonetic distance function. I also experimented with making weakly equivalent variations on a grammar to find one that compiled to a more compact representation (in the end I went with a direct algorithm, and it drastically increased the size of the "language" that we could use in applications).

最近，我将它们用作默认假设，以此来测试由各种算法生成的解决方案的质量。这主要涉及分类和不同类型的拟合问题(即创建一个“规则”，解释审查员对数据集所做的一组选择)。

首先，Jonathan Koza的《遗传编程》(在亚马逊上)几乎是一本关于遗传和进化算法/编程技术的书，有很多例子。我强烈建议你去看看。

As for my own use of a genetic algorithm, I used a (home grown) genetic algorithm to evolve a swarm algorithm for an object collection/destruction scenario (practical purpose could have been clearing a minefield). Here is a link to the paper. The most interesting part of what I did was the multi-staged fitness function, which was a necessity since the simple fitness functions did not provide enough information for the genetic algorithm to sufficiently differentiate between members of the population.

在读完《盲人钟表匠》之后，我对道金斯所说的帕斯卡程序产生了兴趣，他开发了一个可以随着时间进化的生物模型。我对使用Swarm编写自己的程序很感兴趣。我没有画出他画的那些奇特的生物图形，但我的“染色体”控制着影响生物体生存能力的特征。他们生活在一个简单的世界里，可以与彼此和环境决一死战。

生物的生存或死亡部分取决于偶然性，但也取决于它们如何有效地适应当地环境，如何有效地消耗营养物质以及如何成功地繁殖。这很有趣，但也向我妻子证明了我是一个极客。

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。

足球引爆。我建立了一个GA系统来预测每周澳式足球比赛的结果。

A few years ago I got bored of the standard work football pool, everybody was just going online and taking the picks from some pundit in the press. So, I figured it couldn't be too hard to beat a bunch of broadcast journalism majors, right? My first thought was to take the results from Massey Ratings and then reveal at the end of the season my strategy after winning fame and glory. However, for reasons I've never discovered Massey does not track AFL. The cynic in me believes it is because the outcome of each AFL game has basically become random chance, but my complaints of recent rule changes belong in a different forum.

该系统基本上考虑了进攻强度、防守强度、主场优势、每周的改进(或缺乏)以及这些方面的变化速度。这为每支球队在整个赛季中建立了一组多项式方程。可以计算给定日期的每场比赛的获胜者和分数。我们的目标是找到最接近过去所有游戏结果的系数集，并使用该集合来预测接下来几周的游戏。

在实践中，该系统将找到能够准确预测过去90%以上游戏结果的解决方案。然后，它会成功地为即将到来的一周(即不在训练集中的那一周)挑选大约60-80%的比赛。

结果是:略高于中游水平。没有巨额奖金也没有能打败维加斯的系统。不过很有趣。

我从零开始构建一切，没有使用任何框架。

我做了一个完整的GA框架，命名为“GALAB”，解决了很多问题:

定位GSM ANTs (BTS)以减少重叠和空白位置。 资源约束项目调度。 进化图景的创造。(Evopic) 旅行推销员问题。 n -皇后和n -颜色问题。 骑士之旅和背包问题。 魔方和数独谜题。 字符串压缩，基于超字符串问题。 二维包装问题。 微型人工生命APP。 鲁比克难题。
