向量加法系统可逆可达性问题

Vector Addition System Reversible Reachability Problem

Jérôme Leroux

摘要:

向量加法系统的可达性问题是网理论的一个中心问题。这个问题已知是可判定的,但其复杂性仍然未知。而这个问题是EXPSPACE-硬的,没有基本的上限复杂性是已知的。在本文中,我们考虑可逆的可达性问题。这个问题包括决定两个配置是否彼此可达,或者等价地,如果它们在可达图的同一个强连通分量中。我们证明了这个问题是EXPSPACE完全的。作为所介绍的材料的应用,我们描述了一个矢量加法系统的可逆域。

英文摘要:

The reachability problem for vector addition systems is a central problem of net theory. This problem is known to be decidable but the complexity is still unknown. Whereas the problem is EXPSPACE-hard, no elementary upper bounds complexity are known. In this paper we consider the reversible reachability problem. This problem consists to decide if two configurations are reachable one from each other, or equivalently if they are in the same strongly connected component of the reachability graph. We show that this problem is EXPSPACE-complete. As an application of the introduced materials we characterize the reversibility domains of a vector addition system.
