derivatives of regular expressions, was proposed by Brzozowski [4]. Among the well-known con- structions of ϵ-free non-deterministic finite automata (NFA), the . Abstract: Brzozowski’s derivatives of a regular expression are developed for constructing deterministic automata from the given regular expression in the. In this paper,some lemmas of the regular expressions are discussed Also the generalizations of the Brzozowski derivatives are proved as.

Considering all the derivatives of a fixed generalized regular expression Dericatives results in only finitely many different languages. Using the previous two rules, the derivative with respect to an arbitrary string is explained by the derivative with respect to a single-symbol string a. The latter can be computed as follows: From Wikipedia, the free encyclopedia. Given a finite alphabet A of symbols, [2] a generalized regular expression denotes a possibly infinite set of finite-length strings of symbols from A.
