Dear Ivan,
Thank you for raising the interesting points on my "Fitness
Causes Bloat" WSC2 paper. I would certainly like to here more about
your work, perhaps we could discuss it outside the WSC2 conference?
Do you have a www home page?

There is some connection between bloat and complexity. Perhaps bloat
highlights a difficulty, in that we are generating huge programs with
the same fitness and identical behaviour. Should we define the
complexity of such bloated programs as being the same as a shorter one
which does the same thing?

We are only using the ant problem as an example of bloat. Much shorter
solutions can be evolved if need be.

Bill
