图像二进制自动机

Image-Binary Automata

Stefan Kiefer, Cas Widdershoven

摘要:

我们在有理数上引入加权自动机的某种限制,称为图像二进制自动机。我们表明,这样的自动机接受的正则语言,可以比相应的NFA指数更简洁,并允许多项式互补,工会和交叉。这与明确的自动机相比,其互补需要一个超多项式状态爆破。我们还研究了无限词版本,图像二进制Büchi自动机。我们表明,这样的自动机是服从概率模型检验,类似于明确的Büchi自动机。我们提供的算法来翻译$k$模糊的Büchi自动机的图像二进制Büchi自动机,导致模型检测算法具有最佳的计算复杂性。

英文摘要:

We introduce a certain restriction of weighted automata over the rationals, called image-binary automata. We show that such automata accept the regular languages, can be exponentially more succinct than corresponding NFAs, and allow for polynomial complementation, union, and intersection. This compares favourably with unambiguous automata whose complementation requires a superpolynomial state blowup. We also study an infinite-word version, image-binary Büchi automata. We show that such automata are amenable to probabilistic model checking, similarly to unambiguous Büchi automata. We provide algorithms to translate $k$-ambiguous Büchi automata to image-binary Büchi automata, leading to model-checking algorithms with optimal computational complexity.
