Left-forbidding cooperating distributed grammar systems

A left-forbidding grammar, introduced in this paper, is a context-free grammar, where a set of nonterminal symbols is attached to each context-free production. Such a production can rewrite a nonterminal provided that no symbol from the attached set occurs to the left of the rewritten nonterminal in the current sentential form. The present paper discusses cooperating distributed grammar systems...

Bidirectional Cooperating Distributed Grammar Systems Bidirectional Cooperating Distributed Grammar Systems

We consider bidirectional cooperating distributed (BCD) grammar systems in the sense of Asveld. Independently of their mode , , =, , or t, BCD grammar systems with two components characterize the re-cursively enumerable languages even with right-linear rules and without-productions. This sharply contrasts earlier results on solely generating or accepting grammars, where right-linear rules alway...

Deterministic Cooperating Distributed Grammar Systems

Subclasses of grammar systems that can facilitate parser construction appear to be of interest. In this paper, some syntactical conditions considered for strict deterministic grammars are extended to cooperating distributed grammar systems, restricted to the terminal derivation mode. Two variants are considered according to the level to which the conditions address. The local variant, which int...

On the Terminating Derivation Mode in Cooperating Distributed Grammar Systems with Forbidding Components

This paper discusses the terminating derivation mode in cooperating distributed grammar systems where components are forbidding grammars instead of context-free grammars. Such systems are called forbidding cooperating distributed grammar systems, and it is demonstrated that the number of their components can be reduced to two without changing the generative power and that these systems are comp...

Cooperating Distributed Grammar systems: A Comparison of Generavite Power

Cooperating Distributed Grammar systems have been introduced for describing multi-agent systems by means of formal grammars and languages. There are currently a lot of variations that differ by generative power. This article is focused on summarize definitions of selected CD grammar systems (homogenous, hybrid, and teams) and comparison of their generative power among themselves and against to ...
