用Kolmogorov复杂性研究形式语言理论

A New Approach to Formal Language Theory by Kolmogorov Complexity

Ming Li, Paul Vitanyi

摘要:

我们提出了一种新的方法来形式语言理论使用柯尔莫哥洛夫复杂性。本文的主要结果是一种泵引理的替代方法,一种正则语言的新刻画,以及一种区分确定性上下文无关语言和非确定性上下文无关语言的新方法。许多例子说明了新的“不可压缩性参数”的使用。这种方法在乔姆斯基层次结构的高端的也是成功的,因为人们可以用柯尔莫哥洛夫复杂度来量化非递归性。(This这是一个未经修正的初步版本。最终版本是发表在SIAM J. COMPUT.上的版本,24:2(1995),398-410.)

英文摘要:

We present a new approach to formal language theory using Kolmogorov complexity. The main results presented here are an alternative for pumping lemma(s), a new characterization for regular languages, and a new method to separate deterministic context-free languages and nondeterministic context-free languages. The use of the new `incompressibility arguments' is illustrated by many examples. The approach is also successful at the high end of the Chomsky hierarchy since one can quantify nonrecursiveness in terms of Kolmogorov complexity. (This is a preliminary uncorrected version. The final version is the one published in SIAM J. Comput., 24:2(1995), 398-410.)
