------------------------------------------------------------------------------

MFCS'91 is the sixteenth in the series of MFCS symposia organized alternatively
in Poland and Czechoslovakia since 1972.  The purpose of the series is to
encourage high-quality research in all branches of Theoretical Computer Science
and to bring together specialists working actively in the area.  Throughout the
years, MFCS served this purpose well, and we hope it will do so in the future.

Principal areas of interest of the symposium include:
	software specification and development, parallel and distributed
	computing, semantics and logics of programs, algorithms, complexity and
	computability theory (this is not an exclusive list).

The scientific programme of the symposium will include 6 invited lectures by
distinguished scientists and 38 presentations selected by the Programme
Committee out of the total 109 submitted papers strictly on the basis of the
scientific merit of the submissions.

MFCS'91 is organized by the Institute of Computer Science of the Polish Academy
of Sciences in cooperation with the Institute of Informatics of Warsaw
University and the Polish Information Processing Society.

LOCATION

The symposium will be held in the hotel/recreation center ``Dom Prasy'' in
Kazimierz Dolny.

	``Dom Prasy''
	ul. Malachowskiego 17
	24-120 Kazimierz Dolny                   tel. (831) 10163

Kazimierz Dolny (on some maps Kazimierz n/Wisla) is a charming small town
beautifully situated on the right bank of the Wisla (Vistula) river some 150 km
south of Warsaw. Its origins date back to the 14th century, with the period of
greatest prosperity in the 15th -- 17th centuries.  Renaissance architecture,
rare in this part of Europe, fully harmonising with the rich natural terrain,
creates the unique atmosphere of this picturesque town and its surroundings.
The view of the Vistula from a nearby hill is truly unforgetable!

TRANSPORTATION

The nearest international airport is Warszawa (Warsaw) with numerous
international connections from all over the world.

From Warsaw, you can reach Kazimierz Dolny by taking a train from
Warszawa-Centralna Railway Station to Pulawy, and then a taxi or bus from
Pulawy to Kazimierz (about 13km). By car, there are two routes from Warsaw.
Either find and follow the signs for Pulawy directly (a shorter, but worse
road) or follow the signs for Lublin and then turn to Pulawy in Kurow. You
should have no trouble finding the signs for Kazimierz Dolny in Pulawy.

There will be special conference buses on Sunday 8th September, leaving at 5pm
from Warsaw for the conference site. The buses, clearly marked with the MFCS
sign, will be waiting by the east entrance to the Palace of Culture and
Science (PKiN), the skyscraper situated in the center of Warsaw, near
Warszawa-Centralna Railway Station. Please mark the appropriate box on the
registration form if you plan to take the conference bus.

To get to PKiN from the international airport, take bus 175.

Bus transportation will be arranged from Kazimierz to Warsaw on the afternoon
of Friday 13th September, and on the morning of Saturday 14th September.

TRAVEL DOCUMENTS

A valid passport and (for citizens of many countries) a Polish entry visa are
required to enter Poland. Visas are issued by Polish consulates and embassies
throughout the world. There should be no problem with this, but as processing
visa applications may sometimes take a few weeks, please apply as soon as
possible. No Polish visas are issued at the Polish border. There is no daily
minimum currency exchange required at present.

ACCOMMODATION AND MEALS

All participants will be lodged in double rooms in the ``Dom Prasy''
hotel/recreation center. Depending on the number of participants, some rooms
may be available for single occupancy, at the extra cost of $50 payable (in
cash) at the beginning of the conference.

Meals will be served at the conference site, beginning with supper on Sunday
8th September, and finishing with breakfast on Saturday 14th September. Please
indicate any special dietary requirements clearly on the registration form.  We
will try to take them into account, within the limited possibilities available.

FEES

The basic inclusive price for the entire conference is $280 per person
(2 650 000 Polish zloty at the current exchange rate). This covers
accommodation and meals, all materials, the excursion, refreshments between
sessions, a welcome drink, the conference banquet and a farewell party.

Participants and/or institutions with limited funds may apply for a reduction
of this price up to 50%. Because of the limited financial resources provided by
the sponsors, the applications for the fee reduction will be considered
individually.

The price for accompanying persons is $150 (1 420 000 Polish zloty at the
current exchange rate) and it does not include the conference materials.

Fees are subject to a 20% surcharge if received after the 30th June deadline.

REGISTRATION

Those wishing to participate in the MFCS'91 symposium should pay the inclusive
conference fee by bank transfer, complete the enclosed registration form and
mail it to the organisers together with a copy of the receipt confirming
payment of the conference fee. It should reach the conference office not
later than 30th June 1991. Receipt of registration will be confirmed.

The number of participants is limited and the Organising Committee reserves the
right to refuse registration after 30th June. Please remember also that
payments reaching us after this date are subject to a 20% surcharge.

PRESENTATION

An overhead projector (25*25cm) and a blackboard will be available. Please make
your transparencies sufficiently readable.  The language of the symposium is
English.  No translation facilities will be provided.

TOURISM

Poland is a beautiful country, and we certainly advocate a few days in Warsaw,
a trip to the Mazurian Lake District, a visit to Cracow or Gdansk, or a hiking
tour in the Tatra Mountains before or after the conference. However, the
conference organisers are not able to directly help you with this. If you need
an extra hotel reservation, advance ticket booking etc., contact a travel
agent. For example:
                                            phone:  ++48-22-26 23 56
