摘要本文基于分解贝叶斯网道义图改进了传播算法的三角化图及连接树的构建.证明了寻找最优三角化图问题可以分解为素块上独立的小的子问题.于是,所有素块的最优三角化图的并即为贝叶斯网的最优三角化图.进一步,我们给出了一个算法,通过连接各个素块的最优三角化图的团树来构建全局最优三角化图的团树.我们进行了模拟实验来展示分解对于求三角化图及连接树的效果. | | 服务 | | ![](http://123.57.41.99/jweb_yysxxb/images/arrow.jpg) | 加入引用管理器 | ![](http://123.57.41.99/jweb_yysxxb/images/arrow.jpg) | E-mail Alert | ![](http://123.57.41.99/jweb_yysxxb/images/arrow.jpg) | RSS | 收稿日期: 2011-04-14 | | 基金资助:国家自然科学基金(11571050,11401047,11371083,11631003,11690012,11571051),吉林省科技发展计划项目(No.20140520059JH)资助项目.
