FO2(<,+1,~) on data trees, data tree automata and branching vector addition systems [PDF]
Logical Methods in Computer Science, 2016 A data tree is an unranked ordered tree where each node carries a label from a finite alphabet and a datum from some infinite domain. We consider the two variable first order logic FO2(

Complexity of Problems of Commutative Grammars [PDF]
Logical Methods in Computer Science, 2015 We consider commutative regular and context-free grammars, or, in other words, Parikh images of regular and context-free languages. By using linear algebra and a branching analog of the classic Euler theorem, we show that, under an assumption that the ...

Synthesis of Data Word Transducers [PDF]
Logical Methods in Computer Science, 2021 In reactive synthesis, the goal is to automatically generate an implementation from a specification of the reactive and non-terminating input/output behaviours of a system. Specifications are usually modelled as logical formulae or automata over infinite

Minimality Notions via Factorization Systems and Examples [PDF]
Logical Methods in Computer Science, 2022 For the minimization of state-based systems (i.e. the reduction of the number of states while retaining the system's semantics), there are two obvious aspects: removing unnecessary states of the system and merging redundant states in the system.

Determinisability of register and timed automata [PDF]
Logical Methods in Computer Science, 2022 The deterministic membership problem for timed automata asks whether the timed language given by a nondeterministic timed automaton can be recognised by a deterministic timed automaton.

Regular Languages in the Sliding Window Model [PDF]
TheoretiCSWe study the space complexity of the following problem: For a fixed regular language $L$, we receive a stream of symbols and want to test membership of a sliding window of size $n$ in $L$.

Weighted Logics for Nested Words and Algebraic Formal Power Series [PDF]
, 2010 Nested words, a model for recursive programs proposed by Alur and Madhusudan, have recently gained much interest. In this paper we introduce quantitative extensions and study nested word series which assign to nested words elements of a semiring. We show

Completing the picture for the Skolem Problem on order-4 linear recurrence sequences [PDF]
TheoretiCSFor almost a century, the decidability of the Skolem Problem - that is, the problem of finding whether a given linear recurrence sequence (LRS) has a zero term - has remained open. A breakthrough in the 1980s established that the Skolem Problem is indeed

Quantitative Automata under Probabilistic Semantics [PDF]
Logical Methods in Computer Science, 2019 Automata with monitor counters, where the transitions do not depend on counter values, and nested weighted automata are two expressive automata-theoretic frameworks for quantitative properties. For a well-studied and wide class of quantitative functions,

, 2020 Computer science class enrollments have rapidly risen in the past decade. With current class sizes, standard approaches to grading and providing personalized feedback are no longer possible and new techniques become both feasible and necessary.
