非确定性句法复杂性

Nondeterministic Syntactic Complexity

Robert Myers, Stefan Milius, Henning Urbat

摘要:

我们引入了一个新的度量正则语言的方法:非确定性语法复杂度。它是句法幺半群的“规范布尔表示”的任何扩展的最小度。等价地,它是任何亚原子非确定性受体的最少数量的状态。事实证明,基本上所有以前的非确定性状态最小性的结构工作计算这个措施。我们的方法依赖于代数解释的非确定性有限自动机作为确定性有限自动机赋予半格结构。重要的是,后者形成了一个自我对偶的范畴。

英文摘要:

We introduce a new measure on regular languages: their nondeterministic syntactic complexity. It is the least degree of any extension of the `canonical boolean representation' of the syntactic monoid. Equivalently, it is the least number of states of any subatomic nondeterministic acceptor. It turns out that essentially all previous structural work on nondeterministic state-minimality computes this measure. Our approach rests on an algebraic interpretation of nondeterministic finite automata as deterministic finite automata endowed with semilattice structure. Crucially, the latter form a self-dual category.
