Dear Colleague:

Thank you for your help with the ``Call for Papers".  We received a very
good collection of research contributions from all over the world.  This
is the first program announcement of the International Logic Programming
Symposium (ILPS91) and ten post-symposium workshops.  The information
consists of latexable versions of the ``Preliminary Program
Announcement'', the ``Registration Form'', the ``Accommodation
Reservation Form''.  Please feel free to use the registration form and
the hotel accomodation form for their intended purpose.  I will again
ask you to distribute the announcement to your fellow colleagues as we
are unaware of all the e-mail and postal addresses.  Please post the
printed version on the department notice boards and circulate the mail
electronically.  We have been making a continuous effort to update our
list of addresses.  However, we understand the limitations of such
effort.  We will need your help to make the symposium a success and a
stimulating site of discussion for research findings.  Please note that
the symposium will also have a poster session (contact: Leon Sterling,
leon@brahms.ces.cwru.edu) and exhibits of the new products and books in
the field of Logic Programming.  Participation in poster sessions and
workshops is still open.  For the workshops entries, please contact the
respective workshop organizers whose e-mail addresses are given in the
preliminary program announcement. 

If you are an ALP member, one of the authors, or recipient of previous
call for papers by post then you are on our mailing list and you will
also receive updated material by post.  If you are not in the above
list and you are considering attending the symposium please send your e-mail
address and/or postal address by e-mail to arvind@mcs.kent.edu (before
July 4, 1991) and ilps91@parc.xerox.com to ensure future communications. 


With best regards,

--Arvind

\leftline{\Large\bf\strut Preface}
\medskip
The 1991 International Logic Programming Symposium\footnote{Previously
called the North American Conference on Logic Programming.} will be held
at the San Diego Princess Resort Hotel from October 28--November 1,
1991. Sponsored by the Association for Logic Programming (ALP), it is
one of
the two major annual conferences on logic programming. This year it is
being held in cooperation with the Association for Computing Machinery
(ACM), the Institute of Electrical and Electronics Engineers (IEEE), and
the American Association for Artificial Intelligence (AAAI).

Originating in the early seventies in the investigation of
computational subsets of first-order logic, logic programming took
hold with the development of efficient implementations of Prolog in
the late seventies. The steady growth and development of the field
since then has established the simplicity, power and elegance of this
approach to computation. Recent years have seen a surge
of interest in logic programming in fields ranging from  artificial
intelligence, programming languages and databases to theoretical
computer science.  Indeed, arising
from logic programming and related areas, exciting new areas of
intellectual inquiry are emerging in the interaction of concurrency,
logic, constraints, algorithms and parallel processing, with the
promise and potential of having a lasting impact on computer science.

To further nurture the development of such areas, a major goal of
this symposium is to promote technical interaction between logic
programming and neighboring fields, including artificial intelligence,
logic, databases and theoretical computer science.  This is reflected in 
the panel of activities scheduled for the symposium. 

Of the 192 papers submitted to the symposium from researchers world-wide,
44 have been selected for presentation at the symposium. In addition,
the symposium features a keynote speech by Robert Constable
(Cornell Univ.),
a  dinner speech by Pat Hayes (MCC), and other invited talks by 
Vladimir Lifschitz (Univ.\ of Texas at Austin), Koichi Furukawa (ICOT) and
Johan van Benthem (Univ.\ of Amsterdam). Several advanced tutorials on
emerging areas 
are also being organized. A special poster session specifically designed
to foster presentation  of material on applications will also be held.
The main body of the symposium will be rounded off by a panel discussion,
chaired by Jean-Louis Lassez (IBM Hawthorne), on the connection between
logic programming and neighboring fields.  The symposium
will be followed by ten post-symposium advanced workshops.

\leftline{\large\bf\strut ACCOMMODATION}

\medskip
\leftline{\bf About the Place}

San Diego County, situated on the Mexico and California border,
is the nation's seventh largest with a population
over two million. San Diego City is California's second largest,
second to Los Angeles. Each year, San Diego attracts thousands of
visitors who are drawn by the climate: sunny, dry, and warm nearly
year-round. They swim, surf, and sunbathe on long beaches facing
the turquoise Pacific. San Diego is famous for its theme parks and 
specialized museums. Sea World, San Diego Zoo (country's finest
zoological/botanical park), Wild Animal Park, and Balboa Park
are must-see attractions.

\bigskip
\leftline{\bf Hotel Information}

The symposium will be held at the San Diego Princess Resort 
Hotel, 1404 West Vacation Road, San Diego, California, 92109-7994.
The Princess has a spacious beach front setting in San Diego's Mission
Bay. Accommodation is in single-level cottage-style suites located at
the beach front.  The hotel forms a peninsula covered with beaches,
lagoons, and tropical flowers. The climate, in general, is warm all
year round; however, warm evening wear is required.  The hotel is
located 10 minutes from downtown San Diego and the international
airport.  Tourist areas, including Sea World, Balboa Park, and
Tijuana---a colorful border town with Mexico, are all within 
convenient traveling distance.


\bigskip
\leftline{\bf Hotel Reservations}

A block of rooms is being held from Sunday, October 27 until Thursday
October 31st, 1991 at a very special symposium rate for ILPS91.  The room rate
will also be valid for three days prior to and following the symposium. 
Students can reduce the accomodation rate by requesting sharing facility
(contact: Pascal Van Hentenryck, pvh@cs.brown.edu).
To make reservations, please use the attached accommodation
reservation form, or call the Princess Resort Hotel at 1.800.344.2626
(from USA) or +1.619.274.4630 (elsewhere)
