Examining grammars and grammatical evolution in dynamic environments

Murphy, Eoin (ACM, 2011-07-12)

This paper is concerned with the effect of the grammar type on grammatical evolution when evolving in dynamic environments. Both representation and dynamic environments have been recognised as important open issues in the ...
Examining mutation landscapes in grammar based genetic programming

Murphy, Eoin ; O'Neill, Michael ; Brabazon, Anthony (Springer, 2011-04-27)

Representation is a very important component of any evolutionary algorithm. Changing the representation can cause an algorithm to perform very differently. Such a change can have an effect that is difficult to understand. ...
Genotype representations in grammatical evolution

Hugosson, Jonatan ; Hemberg, Erik ; Brabazon, Anthony ; O'Neill, Michael (Elsevier, 2010-01)

Grammatical evolution (GE) is a form of grammar-based genetic programming. A particular feature of GE is that it adopts a distinction between the genotype and phenotype similar to that which exists in nature by using a ...
