PRAGMA FEST!

October 22-24 · Krakow · Poland

Workshop on computational social choice

We invite researchers—especially early stage ones— for a workshop on computational social choice (COMSOC), to present their work and discuss their recent progress. We are interested in all areas of COMSOC, with a particular focus on the following:

  • Analysis of voting rules
  • Analysis of approval and ordinal elections
  • Participatory budgeting
  • Axiomatic studies
  • Complexity-theoretic studies
  • Game-theoretic aspects of elections
  • Robustness analysis
  • Preference representation and elicitation
  • Experimental approaches
  • Empirical studies
  • Analysis of data
  • Recommendation systems
  • Judgment aggregation
We expect about 20-40 attendees. We invite you to propose a talk that you would like to give. Depending on the number of attendees, we may not be able to offer slots to everyone, but everyone will be able to present a poster. The choice as to who would give a talk—in case it is needed—will be made to maintain diversity of topics and teams of the attendees.

Lunches / Coffee Breaks / Dinner

We will provide lunches and coffee breaks throughout the workshop. We also invite you for a dinner on one of the evenings.

Registration

Attending the workshop is free of charge, but we request that you register by the end of September. If you miss this deadline but still would like to attend, please send an email Piotr Faliszewski. We will try to accommodate you.

Accomodation

Your accomodation is on you, but we are happy to provide suggestions. In particular, regarding accomodation:
  • Krakow is a major tourist attraction in Poland. There are many small hotels and a few bigger ones. There are also plenty of hostels and apartments for short-term rent.
  • Typical areas where people stay during visits to AGH University are either in the close neighborhood of the university (typically cheaper), or in the Main Square are (more touristy, still walking distance from AGH). It is less frequent to stay in the Jewish Quarter (Kazimierz), but still feasible (possibly using public transport).
  • Poland generally and Krakow specifically are among the safest locations in Europe.

Travel

Travel is on you as well. Here are some options:
  • There is an International Airport Balice in Krakow (code: KRA). In particular, there is a number of low-cost airlines arriving to Krakow. From the airport, there is a very convenient train (SKA1) that stops (station Krakow Lobzow) in the vicinity of the department and at the Krakow Main Train Station (Krakow Glowny). Alternatively, you can take a public bus or a taxi.
  • Arriving by train is easy from a number of locations (e.g., Prague and Vienna).
  • There are also long-range buses (e.g., connecting Berlin).

Photos

It is not impossible that when you come in the end of October, it will be somewhat less sunny, and there may be fewer leaves. Green color might be harder to spot.
