TUTORIAL SESSIONS
______________________________________________________________________
1A. "Semantics of Concurrent Constraint Programming Languages",
Vijay Saraswat, Xerox PARC, USA
This tutorial surveys work in semantics of concurrency, with focus on
the model theory of concurrent constraint programming languages. In
this light, we present various models for determinate and
indeterminate cc languages and discuss their inter-relationships.
1B. "Types and Polymorphism",
Uday Reddy, Univ. of Illinois, USA
This tutorial reviews the major directions in designing type systems
for logic programming languages including those based on conventional
mathematical notions of types, those using regular tree sets as types,
and those based on "descriptive" types. Connections with extant
theories of types and type inferencing issues are discussed.
2A. "Deductive Databases -- Systems and Languages",
Carlo Zaniolo, MCC, USA
In order to provide a logic programmer with the skills needed to
develop applications on deductive database systems, we will contrast
their semantics, enabling technology and programming styles to those
of Prolog.
3A. "Constraint Logic Programming-from Theory to Applications",
Pascal Van Hentenryck, Brown Univ., USA
This tutorial overviews, theory, design and applications of CLP in the
computation domains of Linear Rational (Real), Arithmetics, Boolean
Algebra, Finite Domains, Presburger Arithmetics and data structures.
3B. "Parallel Implementation of Prolog",
Andrzej Ciepielewski, SICS, Sweden
This tutorial will overview approaches and techniques for
parallelizing Prolog, including AND-, OR- and AND/OR- models,
shared/distributed memory, side- effects, compile time analysis, and
some existing prototypes.

SOCIAL EVENTS
Sunday, October 28, 7:00-9:00pm
OPENING RECEPTION
Held in the Hyatt Regency Hotel, this complimentary reception
offers an opportunity to meet other attendees before the four days of
the conference.
Wednesday, October 31, 7:00pm
CONFERENCE HALLOWEEN BANQUET
Held in Hyatt Regency Hotel, this formal dinner will include a
speech by Professor Raymond Smullyan, on "Puzzles and Paradoxes" -- a
fitting prelude to the Halloween extravanganza on Sixth Street.
Other Events will be announced at a later date.
AREA ATTRACTIONS AND WEATHER INFORMATION
The conference hotel is in a midtown location on the shore of
Town Lake, and offers miles of jogging and cycling nature trails. The
city's central business district is just six blocks away.
Austin is a lush green city in the heart of the Texas Hill
Country. The many surrounding lakes and rivers make Austin appealing
for swimming and boating.
With one of the largest concentrations of artists in the USA,
Austin's live entertainment and arts scene is thriving. On Sixth
Street and at Antone's, they say, one can find the best blues west of
the Mississippi.
The nearby Sixth Street is also renowned for its colorful
Halloween parade.
In the Fall, Austin's weather is mild, with an average daytime
temperature of 80F and an average nighttime temperature of 58F.
