非耐冷VASS的普适性问题

Universality Problem for Unambiguous VASS

Wojciech Czerwiński, Diego Figueira, Piotr Hofman

摘要:

我们研究无歧义VASS语言,即具有状态的向量加法系统,其转换从有限字母表中读取字母,并且其接受条件由一组最终状态定义(即,的语言)。我们表明,明确的VASS的普遍性的问题是ExpSpace完整的,在纯粹的对比,阿克曼完整的任意VASS,即使在1维。当维数d固定时,如果d至少为2,则普适性问题是PSpace完全的,并且对于1维VASS(也称为单计数器网)是coNP困难的。

英文摘要:

We study languages of unambiguous VASS, that is, Vector Addition Systems with States, whose transitions read letters from a finite alphabet, and whose acceptance condition is defined by a set of final states (i.e., the coverability language). We show that the problem of universality for unambiguous VASS is ExpSpace-complete, in sheer contrast to Ackermann-completeness for arbitrary VASS, even in dimension 1. When the dimension d is fixed, the universality problem is PSpace-complete if d is at least 2, and coNP-hard for 1-dimensional VASSes (also known as One Counter Nets).
