正则可实现性问题与正则语言

Regular realizability problems and regular languages

Alexander A. Rubtsov

摘要:

我们研究正则可实现性(RR)问题,这是验证一个正则语言-问题的输入-和固定的语言称为过滤器的交集是否为非空的问题。考虑了两类依赖于正则语言表示的问题。如果输入上的正则语言由DFA表示,则我们得到(确定性)正则可实现性问题,并且我们证明了在这种情况下,对于任意正则过滤器,正则可实现性问题的复杂性是L-完全的或NL-完全的。我们还表明,在NFA的输入表示正则语言的情况下,问题总是NL-完全的。

英文摘要:

We investigate regular realizability (RR) problems, which are the problems of verifying whether intersection of a regular language -- the input of the problem -- and fixed language called filter is non-empty. We consider two kind of problems depending on representation of regular language. If a regular language on input is represented by a DFA, then we obtain (deterministic) regular realizability problem and we show that in this case the complexity of regular realizability problem for an arbitrary regular filter is either L-complete or NL-complete. We also show that in case of representation regular language on input by NFA the problem is always NL-complete.
