Vitalenergie (Qi) und Blut (Xue),-transducers. Several results (camplexity and efficiency) are established, same new and other previously proved only in special cases. As an application, we show that for every family of deterministic context-free pushdown parsers (e.g. precedence, LR(k), LL(k), ...) there is a family of general con

At the same time, the methods used imply a new and simple algebraic proof of Parikh’s original theorem, directly transforming an arbitrary context-free grammar into a letter-equivalent regular grammar. Further applications are discussed.

https://doi.org/10.1007/3-211-29992-0It is well known that, for a given context-free grammar G, the recognition problem “x ∈ L(G)” can be decided in 0(|x|). steps by a suitable algorithm. How do extensions behave in this respect? In particular, do they admit recognition algorithms whose time is polynomially bounded by the length of the input?
