交替自动机的余代数决定

Coalgebraic Determinization of Alternating Automata

Meven Bertrand, Jurriaan Rot

摘要:

余代数是目前相当活跃的领域,其目的是从一个非常抽象的角度来看待一般的基于状态的系统(最突出的是自动机),主要使用范畴论的工具。它的成就之一是给出了一个完全通用的确定性方法,以优雅的方式将非确定性自动机,概率自动机或非确定性下推自动机统一在同一个模型中。然而,交替自动机的情况不容易适合这个模型。因此,这次实习的目的是解决这个问题:交替自动机也可以确定在coalgebraic的方式?这是否给出了与具体定义的语义相一致的语义?在本报告中,我们对这两个问题都给予了肯定的回答。我们建构的主要元素是一个分配律,它的定义一段时间以来一直是一个悬而未决的问题。

英文摘要:

Coalgebra is a currently quite active field, which aims to look at generic state-based systems (most prominently automata) from a very abstract point of view, mainly using tools from category theory. One of its achievements is to give a completely generic approach of determinization, unifying in an elegant manner non-deterministic automata, probabilistic automata or non-deterministic pushdown automata in one and the same model. However, the case of alternating automata fails to easily fit in this model. The aim of this internship was therefore to tackle this problem: can alternating automata also be determinized in the coalgebraic way? Does this give semantics that coincides with the concretely defined one? In this report, we give a positive answer to both questions. The main element of our construction is a distributive law, the definition of which has been for some time an open question.
