Meta-grammar constant creation with grammatical evolution by grammatical evolution
Ian J. Dempsey, Michael O’Neill, Anthony Brabazon · 2005
This study examines the utility of meta-grammar constant generation on a series of benchmark problems. The performance of the meta-grammar approach is compared to a grammar which incorporates grammatical ephemeral random constants, digit concatenation, and an expression based approach. It is found that the meta-grammar approach to constant creation is particularly beneficial on the dynamic problem instances in terms of the best fitness values achieved.
