V. K. Ivanov, D. S. Dumina, N. A. Semenov

摘要:

本文针对遗传算法加性适应度函数中权因子解析确定方法的选择问题,提出了一种解决方法。该算法是进化过程的基础,该进化过程在搜索引擎中形成稳定且有效的查询群体以获得高度相关的结果。本文给出了一种算法适应度函数的形式化描述,它是三个异质准则的加权和。详细介绍了所选用的分析确定权重因子的方法。据指出,不可能使用专家评估方法。作者提出了一个研究方法论使用的实验结果,从早期讨论的项目“数据仓库支持的基础智能网络爬虫和进化模型的目标信息选择”。有一个初始数据集的描述,其中包含用于计算权重的数据范围。通过实例说明了计算顺序。研究结果以图形的形式展示了适应度函数在使用各种权重选项的遗传算法操作期间的行为。

英文摘要:

The paper presents a solution for the problem of choosing a method for analytical determining of weight factors for a genetic algorithm additive fitness function. This algorithm is the basis for an evolutionary process, which forms a stable and effective query population in a search engine to obtain highly relevant results. The paper gives a formal description of an algorithm fitness function, which is a weighted sum of three heterogeneous criteria. The selected methods for analytical determining of weight factors are described in detail. It is noted that expert assessment methods are impossible to use. The authors present a research methodology using the experimental results from earlier in the discussed project "Data Warehouse Support on the Base Intellectual Web Crawler and Evolutionary Model for Target Information Selection". There is a description of an initial dataset with data ranges for calculating weights. The calculation order is illustrated by examples. The research results in graphical form demonstrate the fitness function behavior during the genetic algorithm operation using various weighting options.
