A unified model of the LL covering transformations  

Lee Gyung-Ok (한신대학교 정보통신학과)
Abstract
The subclasses of LR grammars, k-transformable grammars, PLR grammars, and extended PLR grammars are LL covering transformable grammar classes. On other hand, their LL covering transformations are based on different formalisms, and hence, the relationship of the transformations is not obvious. This paper gives a unified model of the LL covering transformations, in which each LL covering transformable grammar class generates its transformation as a specific instance.
