Simplicity and the form of grammars
WebbDescriptive grammars contain actual speech forms recorded from native speakers of a particular language and represented by means of written symbols. Descriptive grammars indicate what languages – often those never before written down or otherwise recorded – are like structurally. WebbA derivative-based, functional recognizer and parser generator for visibly pushdown Grammars that accepts ambiguous grammars and produces a parse forest containing all valid parse trees for an input string in linear time is presented. In this paper, we present a derivative-based, functional recognizer and parser generator for visibly pushdown …

Now we have designed grammar for all combinations of a* and b* i.e. (a*b*)*.
