PROGRAMMED GRAMMARS WITH RULE QUEUES

International Journal of Foundations of Computer Science, 2007
We generalise the well-known notion of programmed grammars without appearance checking by introducing a buffer that could store sequences of rules, thus not necessarily describing the rule to be selected in the very next step, but rather in some future time.

Grammar-based program transformation

Proceedings. Conference on Software Maintenance, 1988., 1988
A grammar-based technique is introduced for making sweeping changes, involving substantial restructuring, to large-scale software programs. Pervasive structural changes are often required to make changes in data structures, computational forms, or programming style during software maintenance. The concept of a grammar-based editor is introduced.

On the borderline between grammars and programs

1991
We describe some of the engineering considerations and trade-offs in the design of a new Compiler Description Language, CDL3. The language is based on Extended Affix Grammars, where the affix rules are used to define tree types. The execution model is deterministic and depth-first, except that part of the work can be delayed until a second pass over ...

Automatic Grammar Induction for Grammar Based Genetic Programming

2015
This paper discusses selected aspects of evolutionary search algorithms guided by grammars, such as Grammar Guided Genetic Programming or Grammatical Evolution. The aim of the paper is to demonstrate that, when the efficiency of the search process in such environment is considered, it is not only the language defined by a grammar that is important, but

Direction controlled programmed grammars

Acta Informatica, 1972
A generalization of the notion of a context-free grammar is presented here. It is based on the notion of a programmed grammar. When the underlying context-free rules do not contain erasing, the class of languages obtained is identical with the class of context-sensitive languages.

Improving Determinization of Grammar Programs for Program Inversion

2013
The inversion method proposed by Gluck and Kawabe uses grammar programs as intermediate results that comprise sequences of operations (data generation, matching, etc.). The determinization method used in the inversion method fails for a grammar program of which the collection of item sets causes a conflict even if there exists a deterministic program ...

Grammar Bias and Initialisation in Grammar Based Genetic Programming

2012
Preferential language biases which are introduced when using Tree-Adjoining Grammars in Grammatical Evolution affect the distribution of generated derivation structures, and as such, present difficulties when designing initialisation methods. Similar initial populations allow for a fairer comparison between different GP methods.

Programming the PTQ Grammar in XSB

1995
The XSB language is an implementation of the Prolog programming language that supports tabling. Since tabling introduces a bottom-up component to the computation, it is essentially an in-memory implementation of a deductive database system. In particular, it is an implementation of SLG-def resolution, a subsystem of SLG resolution [1].The resulting ...
