The workshop was a roundtable open discussion, moderated by W. B. Langdon, where key proponents of the different approaches to theory listed below gave short talks in support of their approach (and against others). Following the coffee break less formal discussions were held in the round.

**Michael Vose** Microscopic models - Markov chains.

**Kalyanmoy Deb** Approximate-models-that-work

**Lashon Booker** Inspiration from Population biology.

**Chris Stephens** Coarse graining (schema-based) approaches

**Dirk Thierens**
felt that the goal of GA theory should be practical and
therefore scalable genetic algorithms.
Experimental analysis is important to test and guide development of
theory.

Steve Gustafson (University of Nottingham) is interested in the parallel between the struggle in biology to ``prove'' evolution and that in evolutionary computation to prove some theory or ``schema theorem'', especially in genetic programming.

Riccardo Poli said that new Schema Theorems are true equalities which
allow one to predict exactly the expected characteristics of the
population at the next time step. As a result exact schema theorems
can also be used *backwards* through time. I.e. to find under which
conditions at the previous generations a GA or GP system can be
expected to be in a given state at a particular generation with a known
probability.

While neither Jon Shapiro nor Adam Prugel-Bennett were present, there was a brief discussion on their statistical thermodynamics approach to genetic algorithm theory.

- Hans Georg-Bayer has organised a Dagstuhl seminar.
- Should someone organise a similar event at the next GECCO'2002?
- The next FOGA workshop will be held in Spain 4-6 September 2002.

May be a more formal record of these discussions is needed?
