Language Classes Generated by Tree Controlled Grammars with Bounded Nonterminal Complexity
A tree controlled grammar is specified as a pair (G,G) where G is a context-free grammar and G is a regular grammar. Its language consists of all terminal words with a derivation in G such that all levels of the corresponding derivation tree – except the last level – belong to L(G). We define the nonterminal complexity Var(H) of H = (G,G) as the sum of the numbers of nonterminals of G and G. In...
متن کاملNonterminal complexity of tree controlled grammars
This paper studies the nonterminal complexity of tree controlled grammars. It is proved that the number of nonterminals in tree controlled grammars without erasing rules leads to an infinite hierarchy of families of tree controlled languages, while every recursively enumerable language can be generated by a tree controlled grammar with erasing rules and at most nine nonterminals. © 2011 Elsevie...
متن کاملRefining the Nonterminal Complexity of Graph-controlled Grammars
We refine the classical notion of the nonterminal complexity of graph-controlled grammars, programmed grammars, and matrix grammars by also counting, in addition, the number of nonterminal symbols that are actually used in the appearance checking mode. We prove that every recursively enumerable language can be generated by a graph-controlled grammar with only two nonterminal symbols when both s...
متن کاملDescriptional Complexity of Three-Nonterminal Scattered Context Grammars: An Improvement
Recently, it has been shown that every recursively enumerable language can be generated by a scattered context grammar with no more than three nonterminals. However, in that construction, the maximal number of nonterminals simultaneously rewritten during a derivation step depends on many factors, such as the cardinality of the alphabet of the generated language and the structure of the generate...
متن کاملon the teacher-generated v.s. leaner-generated noticing-the-gap activities in language classes
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
