The Finite Graph Problem for Two-Way Alternating Automata
نویسنده
چکیده
Two-way alternating automata on trees were introduced by Vardi [Va98]. Here we consider alternating two-way automata on graphs and show the decidability of the following problem: ,,does a given automaton with the Büchi condition accept any finite graph?” Using this result we demonstrate the decidability of the finite model problem for a certain fragment of the modal μ-calculus with backward modalities.

Distributed Graph Automata and Verification of Distributed Algorithms
Combining ideas from distributed algorithms and alternating automata, we introduce a new class of finite graph automata that recognize precisely the languages of finite graphs definable in monadic second-order logic. By restricting transitions to be nondeterministic or deterministic, we also obtain two strictly weaker variants of our automata for which the emptiness problem is decidable. As an ...
متن کاملUnconventional Finite Automata and Algorithms
We investigate several unconventional models of finite automata and algorithms. We show that two-way alternating automata can be smaller than fast bounded-error probabilistic automata. We introduce ultrametric finite automata which use p-adic numbers to describe the branching process of the computation. We examine the size complexity of all the abovementioned automata for the counting problem. ...
متن کاملClassical and quantum realtime alternating automata
We present some new results on realtime classical and quantum alternating models. Firstly, we show that the emptiness problem for alternating one-counter automata on unary alphabets is undecidable. Then, we define realtime private alternating finite automata (PAFAs) and show that they can recognize some non-regular unary languages, and the emptiness problem is undecidable for them. Moreover, PA...
متن کاملA Playful Glance at Hierarchical Questions for Two-Way Alternating Automata
Two-way alternating automata were introduced by Vardi in order to study the satisfiability problem for the modal μ-calculus extended with backwards modalities. In this paper, we present a very simple proof by way of Wadge games of the strictness of the hierarchy of Motowski indices of two-way alternating automata over trees.
متن کاملEmptiness of Linear Weak Alternating Automata
The automata-theoretic approach to model checking requires two basic ingredients: a translation from logic to automata, and an algorithm for checking language emptiness. LTL model checking has traditionally been based on (generalized) Büchi automata. Weak alternating automata provide an attractive alternative because there is an elegant and linear-time translation from LTL. However, due to thei...
