UPDATED 4/16/91 You have reached the info center for the STOC '91 conference. This info file is automatically bounced back to you. If you need more information, please contact Jeff Vitter (jsv@cs.brown.edu) or Cris Koutsougeras (ck@rex.cs.tulane.edu) ---------------------------------------------------------------------- ADDITIONAL HOTEL INFO IS INCLUDED IN THIS MESSAGE ---------------------------------------------------------------------- SETTING UP A TEMPORARY MAILING LIST We are setting up a temporary mailing list for exchanging information about the conference. You may find this communication means convenient in your search for accomodation or transportation or prearranging meetings. If you would like to come in contact with other attendants of the STOC91 conference send a message to ck@rex.cs.tulane.edu asking for signup. If you want your message distributed send it to ck@rex.cs.tulane.edu but include in the subject line the words "STOC-D". ---------------------------------------------------------------------- APPEALING FOR RELEASING RESERVATIONS WHICH ARE NOT NEEDED. We had reserved 250 rooms at the Marriot for the conference. All those rooms are booked and people now face regular room rates. Since we are past the deadline which Marriott set for reduced rates rooms which will be released will be made available to the public at regular rates and without particular preference to STOC attendees. However, Marriot will accept transfers of rooms reserved without changing the rates. If you have a reservation which you cannot use please find someone who wants it and arrange a transfer of the reservation to the new name. For this purpose you may find the above mentioned mailing list ideal so you are urged to sign up. ---------------------------------------------------------------------- Acknowledgements that registrations have been received are automatically sent through e-mail as soon as a registration is processed. We do not send such acknowledgements through US-mail. If you have sent a registration and have not received a response within two weeks, please contact ck@rex.cs.tulane.edu. ---------------------------------------------------------------------- Please note a change of room for the Sunday nite, May 5 reception. It will be in the Mardi Gras Ballroom, Salons D-E, 3rd floor. It will not be in La Galerie. ---------------------------------------------------------------------- A call is included in the end of this file for the upcoming IJCAI-91. ---------------------------------------------------------------------- The STOC '91 Advance Program that was recently mailed to all SIGACT members by ACM has several errors and typos in it. ACM accidentally sent the uncorrected galleys rather than the corrected galleys to the printer for final printing! The corrected program will be distributed at the conference. Here are some of the corrections/updates to what ACM sent: 1. On the Advance Registration form, please be *sure* to include your ACM Membership number if you are registering as an ACM or SIGACT member. 2. My correct telephone number is (401) 863-7646. 3. The 800-number for the Jazz and Heritage Festival is (800) 683-1996. Besides the festival at the Fairgrounds racetrack Thursday-Sunday, there are also separate concerts headlined by Alan Toussaint (May 1, 8pm) La Noche Latina (May 2, 7:30pm) Count Basie and Cab Calloway Orchestra (May 3, 8pm) Robert Cray Band, John Lee Hooker, and the Radiators (May 3, 9pm) Jackie McLean quartet with the Harper Brothers (May 4, 8pm) The Neville Brothers (May 4, 9pm) D. Harrison and D. Marsalis (May 4, midnite) There are also numerous typos in the ACM version. Sorry for the confusion. -- Jeff ----------------------------------------------------------------------- The rest of this file is the STOC '91 Advance Program.

Student registration includes all of the above except the banquet. Creole and Cajun hors d'oeuvre will be served at the reception, and local refreshments will be served at the business meeting. The banquet includes entertainment by a traditional New Orleans jazz band. Extra banquet tickets are available for \$40 and can be purchased with registration or preregistration. The registration desk will be open outside the reception in La Galerie, second floor, on Sunday night from 8--11~pm. On Monday to Wednesday, there will be a registration and information desk set up outside the Acadia Ballroom on third floor from 8~am to 5~pm. \paragraph{Proceedings} Additional copies of the STOC '91 proceedings will be available at the registration desk, on a first come, first served basis. \paragraph{Hotel Information} The conference will be held at the New Orleans Marriott Hotel, 555 Canal Street, New Orleans, LA~70140 ((504) 581--1000). The Marriott is a first-class hotel conveniently located in downtown New Orleans at the corner of Canal Street and Chartres, on the edge of the beautiful French Quarter. A block of rooms is being held from Saturday, May 4 until Saturday morning, May 11, at a very special symposium rate for STOC '91 and the subsequent Workshop on Parallel Algorithms. The daily rates per room are \$109 (single, one-bed double, or two-bed double), \$129 (triple), and \$139 (quad). See the hotel reservation form for more information. Reservations received after the cut off date of April 5, 1991 or after the room block is filled are subject to limited availability and might not be available at the group rate. Our group room rates are very inexpensive compared to those of other hotels, so please reserve early. If rooms run out, extra rooms might be found nearby at the Sheraton New Orleans Hotel ((504) 525--2500), Hotel Le M\'eridien New Orleans ((504) 525--6500), or the Monteleone Hotel ((504) 523--3341). \paragraph{Child Care} The Marriott does not have an in-house babysitting service, but can provide a list of babysitters upon request. \paragraph{Airline Information} United Airlines has been designated as the official airline of STOC~'91 and is offering special fares between May~2 and May~12. >From U.S. cities, the discount is 45\% off unrestricted coach fares when purchased three days in advance and 5\% off any restricted fares. Separate discounts are available for flights from Canadian cities. There may also be discounts on international United flights if there is sufficient booking. To obtain this convention discount, you must call Pearson Travel (ARC No.~41801863), 93 Dyer Street, Providence, R.I.~02903. The phone number during business hours is (800) 729--2500 (toll-free from the U.S. or Canada). After business hours, for emergency use, you can call (800) 343--5032 (toll-free from the U.S. only) or (617) 262--5000. \paragraph{Transportation} New Orleans International Airport (MSY) is served by most major airlines. The airport is located just west of the city, about 14 miles from downtown. Rhodes shuttles will take you to the Marriott for about \$7 per person; you can board them near the Delta airlines baggage claim. Taxi fare is approximately \$18 total for 1--3 people, \$24 for four people, and \$30 for five people. To reach the hotel by car from the airport or points west, follow the signs to I-10 East. Stay on I-10 East about 10.5 miles and follow the signs all the way to the SUPERDOME. (Think SUPERDOME.) Here are the more detailed directions: While on I-10 East, be careful to avoid accidentally getting onto I-610 to Slidell at exit~231; that exit is on the left so you have to stay on the right to remain on I-10 to the business district. The exit you want is Exit~234A, which is 3.5 miles later and is also on the left-hand side. Take Exit~234A (U.S.~90--SUPERDOME--CLAIBORNE AVE.--WESTBANK) from the left-hand lanes; quickly get to the middle lane and take the SUPERDOME--CLAIBORNE AVE.\ turnoff. Keep following the signs to the SUPERDOME. When you finally reach the Superdome, at the bottom of the ramp, turn left. The road winds around the Superdome and eventually merges onto Poydras Street. Continue on Poydras about 0.6 miles and turn left onto one-way Tchoupitoulas Street (immediately before the Holiday Inn Crowne Plaza). Proceed a couple blocks to Canal Street, the next big intersection. Turn left onto Canal Street. The Marriott will be just ahead on the right. You can turn into the Marriott garage at the entrance. To reach the hotel by car from points east, enter New Orleans on I-10 West. Take Exit~235B (CANAL STREET--SUPERDOME). After you get off the exit ramp, go one block to the light. Turn right; you'll now be on Canal Street. Proceed about 0.9 miles. The Marriott will be on your left. Pass it, make a U-turn at the indicated place on the neutral ground (being careful not to run into a city bus), and pull into the Marriott garage. The arrival point for Greyhound buses and Amtrak trains is the Union Passenger Terminal, which is about one mile from the Marriott. Regular train service extends to Houston and California, to Chicago (on the City of New Orleans), and to Atlanta and the east coast. \paragraph{Workshop on Parallel Algorithms} The 2nd Annual Workshop on Parallel Algorithms (WOPA 2) will be held at the New Orleans Marriott immediately after STOC '91, on Thursday, May 9 and Friday, May 10. Registration is \$50 (\$20 for students) and includes two lunches, a reception on May~9, and conference materials. Student fellowships are available. Contact Dawn Vance at (301) 405--6730, dawn@umiacs.umd.edu, for more information. \paragraph{Things to See, Do, and Eat.} New Orleans (pronounced ``Noo AW-lins'') is deservedly nicknamed America's Most Interesting City. It is world-renowned for its European flavor and is ideal for walking, touring, shopping, and dining. It also boasts one of the world's largest ports. The New Orleans Marriott Hotel is on the border of the historic French Quarter, the city's most famous site. The French Quarter (known locally as the Vieux Carr\'e) consists of 70-odd city blocks that formed the original settlement founded in 1718 by the French brothers Bienville and Iberville. The Quarter's architecture and lacework balconies are actually Spanish, fashioned during Spain's rule during the last half of the 18th century. One block from the hotel is Royal Street, where you can find scores of interesting antique shops and art galleries. One more block brings you to Bourbon Street's many restaurants and night clubs. Mahogany Hall (near the start of Bourbon) and Preservation Hall (just off Bourbon on St.~Peter) are great and inexpensive places to hear traditional jazz. (Be sure you get a seat at Preservation Hall; you might have to stand in back for the first set.) Picturesque Jackson Square, with its centerpiece statue of Andrew Jackson, hero of the Battle of New Orleans, is bounded by Chartres, St.~Peter, St.~Ann, and Decatur Streets. On the Chartres side of the square is the Cabildo (the former Spanish seat of government), St.~Louis cathedral (one of the oldest and most photographed churches in the U.S.), and the Presbyt\`ere. Both the Cabildo and Presbyt\`ere now serve as museums. On the opposite side are the Mississippi River, the renovated Jax Brewery shopping mall, and Caf\'e du Monde, which serves its famous beignets (doughnuts) and strong caf\'e au lait (with chicory) 24 hours a day. Most of the city is below sea level, so you have to walk up to see the river. The French Market is the portion of the French Quarter starting at Caf\'e du Monde and extending downriver. Walking tours of the French Quarter are available from the National Park Service (in the French Market, 916 N.~Peters Street, 589--2636) and the Presbyt\`ere (523--3939). The brand new Aquarium of the Americas is a couple blocks from the Marriott on the Mississippi River at the foot of Canal Street. It ranks as one of the best aquariums in the world. It houses more than 7,500 specimens of marine life found throughout the Americas. There is a streetcar line along the river that runs from the French Market to the Riverwalk mall and convention center. The large Hilton hotel at the Riverwalk is home to Pete Fountain's jazz club. The streetcar makes several stops, including Jax Brewery, the Aquarium, and Canal Street. You can take a boat or hydrofoil on the Mississippi River from the Aquarium's dock to the popular Audubon Park Zoo in the uptown section of the city. The zoo encompasses 58 acres of simulated natural habitats and more than 1,500 animals, many of them rare and exotic. The front part of Audubon Park faces Tulane and Loyola Universities. The St.~Charles streetcar, the oldest continuously-operated commuter rail line in America, runs regularly from Canal Street along St.~Charles and Carrollton Avenues. It is a nice one-mile walk or jog from the Tulane University carstop through Audubon Park to the zoo. You get to see some beautiful uptown mansions, the Garden District, and De La Salle High School (where one conference co-chair graduated) along St.~Charles Avenue. Other city attractions include the New Orleans Theater of the Performing Arts, the New Orleans Philharmonic-Symphony Orchestra, the Louisiana Superdome, the New Orleans Museum of Art in City Park, river and bayou cruises, antebellum homes on the Mississippi River, and many excellent places to hear jazz and New Orleans rhythm and blues. Three places of note in the uptown section of the city are Tipitina's (on Napoleon Avenue near the river), Maple Leaf (on Oak Street off Carrollton), and Tyler's (on Magazine). Information on the well-known Jazz and Heritage Festival is given below. New Orleans and its environs are also a sportsman's paradise, offering superb opportunities for golf, fishing of all types, tennis, horseracing, and professional sports. There are several nice jogging routes around the French Quarter and the river. And if you have any time left after all that, the technical talks at STOC '91 are supposed to be pretty good. New Orleans is home to such Creole and Cajun specialties as beignets, strong coffee and chicory, red beans and rice (the traditional Monday meal), jambalaya, crawfish \'etouf\'ee, shrimp cr\'eole, softshell crab, blackened redfish, turtle soup, gumbo, crawfish bisque, oysters Rockefeller and Bienville, eggs Benedict and eggs Sardou, po-boy sandwiches (made on French bread, sliced lengthwise), oyster and shrimp loaves (fried seafood po-boys), muffalettas (Italian coldcut and oil sandwiches sold at Central Grocery in the French Market), Ramos gin fizzes, \dots~and the list goes on and on. World-class restaurants such as Antoine's, Galatoire's, Brennan's, Arnaud's, and K-Paul's are in the French Quarter just a few blocks away from the Marriott, and Emeril's is near the convention center. (Men: some restaurants require a coat and tie.) Oyster bars like Felix's, Acme, and the Pearl are even closer. Further information on sights and dining will be available at the registration desk. The French Quarter is full of tourists at night, especially on Bourbon Street and near Caf\'e du Monde, and is considered safe. We recommend that you avoid wandering off to the areas northwest of the French Quarter, on the other side of North Rampart and Basin Streets (six blocks from the Marriott in the direction away from the river), where there is a higher incidence of neighborhood crime. \paragraph{Jazz and Heritage Festival} An excellent incentive to arrive a day or two early, besides getting cheaper airfares, is the world-famous Jazz and Heritage Festival, which will be concluding the Thursday--Sunday immediately before STOC~'91. The festival brings together a host of great names in traditional jazz, modern jazz, rhythm and blues, and gospel. It also has several local food and crafts booths. The festival takes place at the Fairgrounds race track near City Park, 11~am--7~pm. Besides the two main stages, there are 10 other side stages and tents. The seating at the main stages is informal, and most people sit on blankets in the infield. Chair seating is available in the tents. Tickets cost about \$7; no advance tickets are needed. There are also several concerts given throughout the week at various auditoriums in the city. Call (800) 683--1996 or (504) 522--4786 to order reserved seats in advance. \paragraph{Climate} Early May weather is very nice in New Orleans.

The area code for all is (504). Toll free numbers are given also in parentheses but the perons likely to answer those numbers would be from the national headquarters and not necessarily from New Orleans. There are too many hotels in New Orleans but the ones provided bellow are the most convenient ones although not the cheaper ones. If you choose any of the folowing list make sure that you are dealing with the resort which is on the street indicated. There are more than one hotels with the same name. The conference takes place immediatelly after the famous Jazz Festival and because of it New Orleans will be flooded with visitors. So do not wait to make arrangements for accomodation. If you are going to have a car and you are considering accomodation in the suburbs then you may consider some hotels in Metairie (on or around the intersection of I-10 and Causeway) which is close to the airport. Metairie has easy access to the Downtown and it is about 9 miles highway driving (in the mornings however I-10 may not be that fast). The Marriot is on Canal Street which is the main Downtown street. Poydras runs paraller to Canal and it is only a couple of blocks away from Canal. Saint Charles runs perpendicular to Canal and Poydras. There are some good hotels on St. Charles but they are not very close to Marriot. However, St. Charles running in the uptown is a beautiful street with Victorian type of houses and on it runs one of the two street car lines. The street car goes all the way to the Downtown.

THEME: ===== The paradigm for the Next Generation of Information Processing Systems will involve large numbers of intelligent agents distributed over large computer/communication networks. Work tasks will be defined by one or more agents and will be executed by a pool of agents acting autonomously, cooperatively, or collaboratively, depending on the resources required to complete the task. A goal of this vision is to be able to efficiently, and transparently, use all computing resources (e.g., processing, knowledge and data) that are available on all computers in large computer/communications network. The design, construction, use, and evolution of systems within the above paradigm will require sophisticated support for all aspects of the systems life cycle. We call such systems Intelligent and Cooperative Information Systems (ICIS). Unlike past major advances in information processing the concept of an ICIS is evolving from several currently disjoint technologies. Artificial Intelligence (AI) can contribute knowledge representation and reasoning techniques, on one hand, and distributed problem solving in a multi-agent environment on the other. Software/Knowledge/Information Engineering can contribute design and development environments/shells and methodologies for building ICIS. These represent only a sample of the component technologies and the contributions they can make to ICIS. Other technologies include Cooperative Work, Distributed Computing, Office Information Systems, and Interoperability. AIM: === In this Workshop we propose to address many aspects of the ICIS functionality, implementation, deployment, and evolution. Thus, the Workshop will provide an ideal forum for exchange of ideas and for identification of the potential roles and nature of the emerging notion of Intelligent Cooperative Information Systems. TOPICS: ======= The Workshop will solicit papers describing original ideas and new results on the foundations and role of ICIS. Suggested topics include but are not limited to: #1 Novel Architectures for ICIS, #2 Advanced Modelling and Reasoning Techniques for ICIS: - Data/Knowledge Representation and Management Techniques for Coordinating Multiple Cooperating Agents, - Techniques for Partitioning and Composing Data and Knowledge, #3 Interoperability Management in Distributed, Heterogeneous Knowledge Bases: - Interfaces, protocols and functionality, - Consistency and Reliability for Shared Knowledge Bases. #4 Cooperative User Interfaces for ICIS ORGANIZING COMMITTEE: ===================== The organizing committee consists of: Mike P.

Holand), Matthew Morgenstern (Xeror Advanced Information Systems), Timos Sellis (Univ. of Maryland), John Smith (CSIRO, Australia), Makoto Takizawa (Tokyo Denki Univ., Japan), Jeffrey Tsai (Univ. of Illinois at Chicago), Ben Wah (Univ. of Illinois at Urbana), Norihiko Yoshida (Kyushu Univ., Japan). The members of the organizing committe, as well as most of the people in the program committte, are involved in the editing of a new international journal on the theme of the Workshop which will appear in March 1992. SCHEDULE: ======== The Workshop will be one day long and wil take place on Sunday, August 25, 1991. There will be four hour sessions (two morning sessions with a break, followed by a lunch break (possibly working lunch), followed by two afternon sessions with a break in between. Session topics will be determined by the issues addressed in the submissions and will correspond to the topics already presented above. Each session will begin with a few overview remarks from one of the program committee members who has refereed the papers for that sesssion and will act as a chairman. This will be followed by a brief presentation (ca. 20 mins) by each of those who had papers accepted for that session topic. This will be folowed by an open discussion on the issues of each session, an wil be mediated by the session chairmain. To maximize interaction atendance will be limited to 35-40 active participants, with no more than 10-12 presentations. SUBMISIONS: ========== Thee will be two kinds of submissions: - Submission of 5 copies of a double-spaced paper not exceeding 5,000 words not later than April 30, 1991 to the organizing committee chairman. The focus of the submissions should be on identification and discussion of key issues concerning ICIS as described above and in particular in the role/solutions that AI techniques can provide, as well as the current status of existing applications. The aim here is to focus on high priority issues for research and to encourage domain experts who have runing or prototyped applications to describe the special requirements of the application that are not addressed by current software as well as their solutions and/or unsolved problems. - Submission of 5 copies of a one-page descriprion of reserach interests and current work (including recent publications) which demonstrates the ability of the potential participant to contribute to the discussions. Domain experts are encouraged to respond in this fashion. Invitations will be primarily issued to those who providwe substantive submissions. The committee wil have the final choice concerning the invitation of participants. All submissions wil be reviewed by the program commitee. the selection of presenters an dparticipants will be based on originality and strength of their submissions as wel as contribution to the field. Presenters and participants will be notified by mid May 1991. Final copy submissions will be made by June 30, 1991. A major publishing company has been approached for publishing the workshop proceedings. Selected papers will be considered for publication in a special issue of intentional journal on ``Intelligent & Cooperative Information Systems'' (IJICIS). IMPORTANT DATES: =============== Deadline for submission: April 30, 1991. Notification of acceptance or rejection: May 1991. Final paper due: June 30, 1991. Conference: August 25, 1991.
