正则表达式,au point

Regular Expressions, au point

Andrea Asperti, Claudio Sacerdoti Coen, Enrico Tassi

摘要:

我们介绍了一种新的技术,用于从正则表达式构建有限状态确定性自动机,基于标记表达式内的一组合适的位置的想法,直观地表示输入字符串的初始前缀处理后达到的可能点。指向正则表达式结合了Brzozowski衍生物的优雅和符号吸引力,以及McNaughton和Yamada标签技术的有效性,基本上结合了两种方法中的最佳方法。

英文摘要:

We introduce a new technique for constructing a finite state deterministic automaton from a regular expression, based on the idea of marking a suitable set of positions inside the expression, intuitively representing the possible points reached after the processing of an initial prefix of the input string. Pointed regular expressions join the elegance and the symbolic appealingness of Brzozowski's derivatives, with the effectiveness of McNaughton and Yamada's labelling technique, essentially combining the best of the two approaches.
