摘要
链接结构是网站设计与维护时需要考虑的主要因素.将网站结构抽象为无权有向图,提出了网页可达性和平均载入时间的概念,建立了一种网站链接结构优化的多目标模型,并针对模型的非线性特点设计了禁忌搜索算法.仿真实验表明,链接结构优化的方法不但有助于管理员维护网站结构,而且可以为电子超市的顾客获取商品信息带来方便.
Link structure is one of the key factors that must be considered when designing and authoring Web sites. By considering the site link structure as a weightless digraph, the concepts of web page accessibility and average loading time were presented. Then, a multi-objective model was built and a tabu search algorithm was proposed to solve this NLP. Simulation results revealed that the method introduced could help the e-supermarket customers to access information more comfortably and assist the site authoring at the same time.
