Keynote lecturers

Martin Dyer, School of Computing, University of Leeds, UK.

Prof. Dr. Martin E. Dyer is from the Computer Science Department of the University of Leeds. He has published over a 100 papers, the majority of them as publication in top-journals in the field or as contribution to proceedings of the most prestigious, highly selective, conferences in the field. Since over 20 years his main research topic is the study of rapidly mixing Markov Chains in relation to approximate counting. In 1991 he won the Fulkerson Prize of the Mathematical Programming Society for his work on computing the volume of convex bodies, essentially a counting problem. The approach is Markov Chain Monte Carlo simulation. The breakthrough was a polynomial bound on the convergence time of this Markov Chain. Since then he has become one of the authorities in this field of approximate counting and approximate uniform random generation.

Khaled Elbassioni, Masdar Institute of Science and Technology, Masdar City in Abu Dhabi, United Arab Emirates.

Khaled Elbassioni is since 2012 an associate professor at Masdar Institute of Science and Technology. He was at the time of the ENUMEX School a senior researcher at Max-Planck Institute for Informatics (from 2006 to 2012). He received B.Sc. and M.Sc. degrees in Computer Science from Alexandria University, Egypt in 1992 and 1995, respectively, and a Ph.D. degree in Computer Science from Rutgers University, USA, in 2002. His main interests are in Theoretical Computer Science, in particular, in the complexity of enumeration problems, approximation algorithms, and game theory.

BiCi events are held in the University Residential Center located in the small medieval hilltop town of Bertinoro. This town is in Emilia Romagna about 50km east of Bologna at an elevation of 230m above sea level. Bertinoro is easily reached by train and taxi from Bologna and is close to many splendid Italian locations such as Ravenna, Rimini on the Adriatic coast, and the Republic of San Marino (all within 35km) as well as some less well-known locations like the thermal springs of Fratta Terme, the Pieve di San Donato in Polenta and the castle and monastic gardens of Monte Maggio. Bertinoro can also be a base for visiting some of the better-known Italian locations such as Padua, Ferrara, Vicenza, Venice, Florence and Siena.

Bertinoro itself is picturesque, with many narrow streets and walkways winding around the central peak. Meetings are held in an archiepiscopal castle that has been converted by the University of Bologna into a modern conference center with computing facilities and Internet access. From the castle you can enjoy a beautiful vista that stretches from the Tuscan Apennines to the Adriatic coast and the Alps over the Po Valley.

How to reach Bertinoro

The University Residential Center is located at Via Frangipane, 6 in Bertinoro (Telephone: +39 0543 446500, Fax: +39 0543 446599).

Bertinoro lies approximately half-way between Bologna and the Adriatic coast town of Rimini. Here is a Google Earth place mark to locate the BiCi complex in Bertinoro. If you are arriving by car, you can obtain driving instructions from most starting points using Google Maps.

For those flying in, the nearest major airport is the Bologna Guglielmo Marconi International Airport (BLQ) which has good connectivity to many major European locations. You may also want to check for flights to the Rimini (RMI) Federico Fellini Airport, reachable from several European cities via low cost companies.

Another possibility, especially for those arriving from North America, is to arrive at one of the two Milan airports (which have direct flights from a number North American cities) then proceed to the Milan Central Train Station, take a train to Forlì, and from there continue by taxi to Bertinoro. Train schedules can be found here.

If you arrive at Rimini Airport, you should take a train (direction Bologna or Milan), get off at Cesena (about a 20-minute trip), and then take a taxi to Bertinoro.

If you arrive at Forlì airport, probably the easiest option for reaching Bertinoro is to hire a taxi. If you arrive at Bologna airport or train station, proceed as indicated below.

Bologna Airport or Train Station to Bertinoro by Taxi

This is going to cost you about 140 EURO, including highway tolls, but it becomes an affordable option if you share it with a group of 3-4 people. For more detailed information, consult or call CoTaBo Taxi.

Bologna Airport to Bologna Center and Train Station

Guglielmo Marconi International Airport, which serves Bologna, is about 10 km to the north-west of the city center. From the airport, you have two options for reaching the train station near the city center:

  • Special “Aerobus” service. The bus runs from 06.00 to 23.35 and makes only 5 stops in the city, the last one being the train station (“Stazione FS”). Tickets may be purchased on board (4,50 EURO). The trip takes around 25 minutes. Between the hours 08.00 and 20.00, the frequency of the bus is approximately once every 15 minutes.
  • Taxi. The trip takes around 15 minutes (barring traffic jams) and should cost less than 20 EURO.

Bologna Train Station to Forlì Train Station

Numerous trains run between Bologna and Forlì. The trip takes 30-45 minutes depending on the train type. Please make sure that you get off at Forlì station and not Forlimpopoli (which is indeed closer to Bertinoro but has no bus service for continuing your trip). For complete train departure times and further information, please consult the Italian Railways web site.

Forlì Train Station to Bertinoro

The simplest way to reach Bertinoro from Forlì is to take a bus. The bus station (located in “via Oriani”) is about 200 mt. from the train station. Buses run from 07.10 (09.10 on Sundays) to 19.35 (19.10 on Sundays). The trip takes around 25 minutes. Another option for reaching Bertinoro from the Forlì train station is to take a taxi. The trip should cost around 20 EURO.

Spending the Night in Bologna

If you are lucky, you can find a room in the very nice, wonderfully located and inexpensive University Guest House. We highly recommend it. The only problem is finding a room. Email bookings are possible through the above site. Otherwise you have to resort
to a hotel. You may book on-line in one of the hotels in the city center.
