Grammar-based Genetic Programming: a survey

open access: yesGenetic Programming and Evolvable Machines, 2010
Grammar formalisms are one of the key representation structures in Computer Science. So it is not surprising that they have also become important as a method for formalizing constraints in Genetic Programming (GP).

Grammar☆

2008
To acquire competence with a natural language, young children must master the grammatical constructions of their language(s). In this chapter we outline the main theoretical issues in the field and trace the developmental path children follow from talking in single unit ‘holophrases’ to using complex, abstract constructions. We describe the development

Grammar Schemata

Journal of the ACM, 1974
A solution is presented for the following problem: Determine a procedure that produces, for each full trio L of context-free languages (more generally, each trio of r.e. languages), a family of context-free (phrase structure) grammars which (a) defines L, (b) is simple enough for practical and theoretical purposes, and (c) in most cases is a subfamily ...

Deterministic grammars and grammar morphisms

Acta Informatica, 1986
The paper deals (in a categorical approach) with the invariance problem of a given parsing property with respect to a given grammar transformation. For this purpose, a deterministic bottom-up parse step is characterized as categorical limit, which allows ''both, systematic grammar type definition and largely strategy-independent invariance proofs.

The Grammar of Grammar

1990
Wittgenstein’s conception of the proper nature of philosophical activity is highly problematic in both his early and later work. The purpose and limits he attributes to philosophy frequently appear to be inconsistent with the substantive results of his own practice of philosophizing.
