Dear Professor McCarthy,

Thank you for your interest in my suggestion of organizing an AAAI
sponsored workshop on the subject of multilevel expert systems that
combine intensive numerical computation with heuristic reasoning.

There are many industrial and scientific problems that would require
expert systems capable not only of reasoning but also of making use of
analytical power of scientific software, such as numerical analysis or 
simulation.  Such expert systems, I believe, will be imbedded in larger
and more traditional software systems.

Not much has been published about the design and the use of such
multilevel expert programs and most of the currently discussed expert
systems are the surface level systems, for example, rule-based.  I have
talked with several attendees of the AAAI-84 Conference and detected
serious interest in the subject.

I suggest the following format of the workshops:

     1.   Topic:  Expert systems combining symbolic reasoning with
          intensive numerical computation.

     2.   Attendance by invitation, limited to about 50 people.

     3.   The workshop will be announced in the AI magazine and 
          potential participants will apply of attendance.

     4.   Place:  Seattle;  date:  Spring or Summer, 1985.

     5.   A brief report with abstracts will be published after the
          workshop.

     6.   The AAAI grant of $5,000 will be used mainly to support
          participants from academia.

I have considerable experience in organizing and chairing scientific
meetings.  In the last two years, I organized and chaired a NATO
supported workshop on high-speed computing in Germany and a Boeing
sponsored conference on, "Computer Science in Aerospace".
                                        Sincerely yours,



                                              Janusz S. Kowalik
