The paper describes an experiment to decide whether GADS is feasible and to explore the effect of some variables on its performance. The results show that GADS can be more efficient than traditional tree-based genetic programming. The experiments reported on in the above abstracts taught me the importance of experimental design. So I am currently working on the experimental design of the explortaion of the GADS technique. But the more I think about it, and plan it, the more subtleties and ideas I come up with.
Statistics plays the key role in the design.
I no longer keep bees - they went when I bought a boat. Brewing I enjoy brewing beer and making wine. I'm still working on making a really good elderberry. For completeness I must say that I also enjoy drinking the stuff. Boating I have a Shetland Family Four which I use to cruise on the Firth of Forth.
