of Michigan is pleased to be hosting:

GPTP-2007 -- Fifth Annual Genetic Programming Theory and Practice Workshop

May 17-19 (Thur-Sat), 2007

Ann Arbor Michigan USA

GPTP is a small, one-track, invitation-only workshop devoted to the

integration of theory and practice. In particular, it focuses on how

theory can inform practice and what practice reveals about theory.

Past workshops have invited speakers to discuss theoretical work

and its value to practitioners of the art, and to review problems and

observations from practice that challenge existing theory.

This year we are asking researchers who are interested in being

invited to present a paper at this Workshop to submit an abstract

representing the work they would like to present. We will extend a

limited number of invitations to participate based on these abstracts.

We especially encourage papers which combine theory with results from

real-world applications, e.g., papers in which theory is used to guide

application to real-world problems, and/or results from real-world

applications that confirm (or contradict) theory. In this vein,

collaborations between "theorists" and "practitioners" are most

welcome, since such collaborations are quite rare but they are likely

to lead to new insights and novel results.

Some of the questions this workshop is expected to address include:

* Does the schema (or other analogous) theorem hold for GP, and what

does this mean for the design and use of GP applications?

* What are good ways to approach the application of GP to a new

problem? What are good ways to adjust control parameters within GP?

Are there heuristics to guide the choice of representation, search

operators, and so on?

* What are the "symptoms" of GP pathology (i.e., premature

convergence, overfitting, etc.)?

* How universal is the behavior of GP over different problems and data types?

* What are the good and bad features of GP for problem application?

* Are there ways to predict whether a problem is "GP tractable?"

* Application of GP to "real" problems, e.g., applications

with large amounts of noisty data, or applications in which GP

must compete with other more accepted approaches.

Note that while debate between theorists is encouraged, the focus

should remain on the implications for GP applications. Similarly,

while "war stories" from application engineers are useful, the choice of

war stories should be made on the basis of understanding the GP

mechanisms, either by addressing why a particular approach worked or

proposing a reason for an unusual behavior.

Papers have been published in a series of "Genetic Programming

Theory and Practice" books, one for each year (by Kluwer/Springer).

The format of this workshop will be similar to that of the previous

workshops (GPTP 2003-2006): a relatively small, invitation-only

workshop on the campus of the University of Michigan in Ann Arbor,

with plenty of time for discussion of a roughly equal mix of a total

of 18 papers by theorists and practitioners. In order to facilitate

a substantial exchange of ideas, workshop talks will be approximately

30 minutes long, with considerable time allocated for discussion.

The papers will be reviewed by co-participants prior to the workshop, and

collected for publication in a book to be published as soon as possible

after the workshop. As we would like to have the papers available for

distribution before the workshop, the likely deadline for the submission

of papers will be mid/late March 2007. Papers will be about 16 pages long.

If you are interested in having a paper considered for presentation

at the workshop and included in the book, please send a one-page abstract

as well as a short CV of the authors to:

gptp-2007@...

by: 7 January 2007. *** Earlier responses are encouraged ***

The abstracts will be reviewed and decisions made by 14 January 2007.

We will select 6-8 proposed papers based on relevance to the GPTP workshop

goals, the expected quality of the contribution, and how the paper topic

will fit with the "mix" of other invited and selected papers.

Note that we will be selecting only high-quality, high-content papers,

i.e., we are looking for papers that have more depth and breadth than

typical conference papers.

Also note there is no "workshop fee" for participation -- the workshop

is funded by donations from groups and companies interested in

advancing the art and science of genetic programming.

If you do anticipate sending an abstract, please let us know as soon

possible, just so we have a rough idea of how many abstract to expect.

If you have questions, please email them to gptp-2007@... .
