在一阶团队逻辑中枚举团队

Enumerating Teams in First-Order Team Logics

Anselm Haak, Arne Meier, Fabian Müller, Heribert Vollmer

摘要:

我们开始研究一阶群逻辑中不同可满足性问题的枚举复杂性。由于我们的许多问题超出了DelP,我们使用了一个框架,用于硬枚举类似于多项式层次结构,这是最近推出的Creamusu等人。2019)。我们证明了在给定的一阶结构中枚举一个固定公式的所有满足队的问题对于依赖逻辑和独立逻辑的某些公式是DelNP-完全的。对于包含逻辑公式,这个问题甚至在DelP中也存在。此外,我们研究了这个问题的变种,只有最大,最小,最大和最小的解决方案,分别考虑。在大多数情况下,这些问题与原始问题具有相同的复杂性。一个例外是包含逻辑的最小变量,它是DelNP完全的。

英文摘要:

We start the study of the enumeration complexity of different satisfiability problems in first-order team logics. Since many of our problems go beyond DelP, we use a framework for hard enumeration analogous to the polynomial hierarchy, which was recently introduced by Creignou et al. (Discret. Appl. Math. 2019). We show that the problem to enumerate all satisfying teams of a fixed formula in a given first-order structure is DelNP-complete for certain formulas of dependence logic and independence logic. For inclusion logic formulas, this problem is even in DelP. Furthermore, we study the variants of this problems where only maximal, minimal, maximum and minimum solutions, respectively, are considered. For the most part these share the same complexity as the original problem. An exception is the minimum-variant for inclusion logic, which is DelNP-complete.
