چکیده

In this paper, we aim to initiate the study of enumeration complexity in the field of dependence logics. Consequently, as a first step, we investigate the problem of enumerating all satisfying teams of a given propositional dependence logic formula without the split junction operator. We distinguish between restricting the team size by arbitrary functions and the parametrised version where the parameter is the team size. We show that a polynomial delay can be reached for polynomials and otherwise in the parametrised setting we reach FPT delay. However, the constructed enumeration algorithm with polynomial delay requires exponential space. We show that an incremental polynomial delay algorithm exists which uses polynomial space only. Negatively, we show that for the general problem without restricting the team size, an enumeration algorithm running in polynomial space cannot exist.

Complexity Results for Modal Dependence Logic

Modal dependence logic was introduced recently by Väänänen. It enhances the basic modal language by an operator =(). For propositional variables p1, . . . , pn, =(p1, . . . , pn−1, pn) intuitively states that the value of pn is determined by those of p1, . . . , pn−1. Sevenster (J. Logic and Computation, 2009) showed that satisfiability for modal dependence logic is complete for nondeterministi...

Equality propositional logic and its extensions

We introduce a new formal logic, called equality propositional logic. It has two basic connectives, $boldsymbol{wedge}$ (conjunction) and $equiv$ (equivalence). Moreover, the $Rightarrow$ (implication) connective can be derived as $ARightarrow B:=(Aboldsymbol{wedge}B)equiv A$. We formulate the equality propositional logic and demonstrate that the resulting logic has reasonable properties such a...

On Quantified Propositional Logics and the Exponential Time Hierarchy

We study quantified propositional logics from the complexity theoretic point of view. First we introduce alternating dependency quantified boolean formulae (ADQBF) which generalize both quantified and dependency quantified boolean formulae. We show that the truth evaluation for ADQBF is AEXPTIME(poly)-complete. We also identify fragments for which the problem is complete for the levels of the e...

Complexity of Model Checking for Modal Dependence Logic

Modal dependence logic (MDL) was introduced recently by Väänänen. It enhances the basic modal language by an operator =(·). For propositional variables p1, . . . , pn the atomic formula =(p1, . . . , pn−1, pn) intuitively states that the value of pn is determined solely by those of p1, . . . , pn−1. We show that model checking for MDL formulae over Kripke structures is NPcomplete and further co...

The Entailment Problem in Modal and Propositional Dependence Logics

We examine the entailment problem for different modal and propositional dependence logics defined in terms of dependence, independence, or inclusion atoms. We establish numerous new complexity results, and settle a long-standing open question by showing that the validity problem for modal dependence logic is NEXPTIME-complete.
