Abstract:

Bouajjani and others presented an automata-based approach to a number of elementary problems on context-free grammars. This approach is of pedagogical interest since it provides a uniform solution to decision procedures usually solved by independent algorithms in textbooks. This paper improves upon previous work in a number of ways. We present a new algorithm which not only has a better space complexity but is also (in our opinion) easier to read and understand. Moreover, a closer inspection reveals that the new algorithm is competitive to well-known solutions for most (but not all) standard problems.
