非迭代概率证明逻辑的复杂性

The Complexity of Non-Iterated Probabilistic Justification Logic

Ioannis Kokkinis

摘要:

逻辑PJ是一个概率逻辑,通过添加(非迭代)的概率运算符的基本理由逻辑J。在本文中,我们建立了上界和下界的逻辑PJ的可导性问题的复杂性。本文的主要结果是PJ中的可导性问题的复杂性与底层逻辑J中的可导性问题的复杂性保持相同,这是PJ中的可导性问题的复杂性,是PJ中的可导性问题的复杂性是PJ中的可导性是PJ中这意味着,概率运算符不会增加逻辑的复杂性,尽管它们可以说丰富了语言的表达能力。

英文摘要:

The logic PJ is a probabilistic logic defined by adding (non-iterated) probability operators to the basic justification logic J. In this paper we establish upper and lower bounds for the complexity of the derivability problem in the logic PJ. The main result of the paper is that the complex- ity of the derivability problem in PJ remains the same as the complexity of the derivability problem in the underlying logic J, which is Πp2-complete. This implies hat the probability operators do not increase the complex- ity of the logic, although they arguably enrich the expressiveness of the language.
