Look at the https://github.com/eclab/ecj/blob/master/ecj/ec/gp/breed/SizeFairCrossoverPipeline.java

Found it fairly doing well in controlling the bloat.

Cheers

Hi Everyone,

In 2008, Poli and McPhee published “Parsimony Pressure Made Easy: Solving the Problem of Bloat in GP.”

In the paper, they outline a fairly straightforward way of controlling mean program size in a GP population.

Has anyone implemented this in ECJ, please? I’d like to use it and don’t want to repeat the effort if it’s already been done.

Thanks!

David
