Thanks to Bob and Tiberiu for their reply. 1) I've downloaded the book on GEP and have started reading it. Without wanting to be controversial, is GEP something truly novel or is it an alternate encoding for GP? I'm no expert in this, moreover anything which promises a big speedup is all good to me... more reading required on my part, I guess. 2) I've briefly looked at the Lawnmower problem and the Parity problem. I don't have a copy of Koza-II, so can someone give a short explanation of the problem? Many thanks.

It supports the Gene Expression Programming variant of genetic programming developed by Dr. Candida Ferreira. It can be simpler to use and I believe is faster and produces quite good results in most cases ... There are quite a few examples included. also Ferreira's book 'Gene Expression Programming; Mathematical Modeling by an Artificial Intelligence' is excellent.

However, I wondering if there are some examples available of how to use the ADF features of ECJ? A tutorial would be outstanding - I'm even happy to write it once I get competent in it :) Thanks in advance Shane Magrath IMPORTANT: This email remains the property of the Australian Defence Organisation and is subject to the jurisdiction of section 70 of the CRIMES ACT 1914.
