Abstract

In this paper, Apical growth Pure context-free grammars (AGPCFG) which are a variation of the pure grammars of Maurer et al are introduced. These grammars allow rewriting of active symbols at the ends of a string simultaneously. They also provide a variation of another kind of grammars called filamentous systems with apical growth, which are motivated by biological considerations. The family of languages generated by AGPCFGs is a subclass of context-free languages. An algorithm for learning this language subclass, in the framework of identification in the limit from positive examples, is provided.
