加权自动机Weighted Automata

Featured Weighted Automata

Uli Fahrenberg, Axel Legay

摘要:

特征转换系统(featured transition system)是一个转换系统,其中的转换是用特征表达式(feature expressions)标注的:布尔表达式(Boolean expressions)是有限数量的给定特征。根据其特征表达式,当存在某些特征时,可以启用每个单独的过渡,而对于其他特征集则禁用。因此,一个有特征的变迁系统的行为取决于一组给定的特征。有一些用于特征转换系统的算法可以一次检查所有特征集的属性,例如LTL或CTL属性。在这里,我们介绍了一个模型的特征加权自动机,它结合了特征转移系统和(半环)加权自动机。我们表明,从加权自动机的方法和技术扩展到功能加权自动机和设计算法来计算定量属性的功能加权自动机的所有功能集在一次。我们展示了应用程序的最小可达性和能量属性。

英文摘要:

A featured transition system is a transition system in which the transitions are annotated with feature expressions: Boolean expressions on a finite number of given features. Depending on its feature expression, each individual transition can be enabled when some features are present, and disabled for other sets of features. The behavior of a featured transition system hence depends on a given set of features. There are algorithms for featured transition systems which can check their properties for all sets of features at once, for example for LTL or CTL properties. Here we introduce a model of featured weighted automata which combines featured transition systems and (semiring-) weighted automata. We show that methods and techniques from weighted automata extend to featured weighted automata and devise algorithms to compute quantitative properties of featured weighted automata for all sets of features at once. We show applications to minimum reachability and to energy properties.
