# Call for Bids to Host COMSOC 2027

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

It is my pleasure to open the call for bids to host **COMSOC 2027**,
the 11th International Workshop on Computational Social Choice.

In previous years, COMSOC has been held as a 3- to 4-day meeting
attracting around 100 participants. The workshop usually has 3-5
invited talks and 40-60 contributed papers (oral and poster). In 2008
and 2010 the workshop was preceded by an extra day of introductory
tutorials, and in 2016 by an industry day. These additional events
were attended by more than half of the workshop participants.

## How to Submit a Bid

If you would like to host COMSOC 2027, please email your bid to:

- **Jiehua Chen** (primary contact): jiehua.chen@ac.tuwien.ac.at

or to one or more other members of the COMSOC steering committee:

- **Omer Lev**: omerlev@bgu.ac.il
- **Marcus Pivato**: marcuspivato@gmail.com
- **Péter Biró**: biro.peter@krtk.elte.hu

**Deadline: 15 June 2026.**

We encourage everyone to apply. However, please bear in mind that we
aim for COMSOC to balance between locations that are geographically
convenient for large segments of the community (mainly Europe and
North America) and locations with potential for growth.

## What to Include in Your Bid

**(1) Location and Facilities.** Where do you propose to hold COMSOC
2027? Please state both the city and the exact venue, and comment on
the suitability of the available facilities for the scientific program
as well as for lunches and coffee breaks. Please also comment on the
accessibility and attractiveness of the location, and on the
availability of suitable accommodation (including low-budget options)
and transport.

**(2) Organization.** Who would be the main local organizer? Which
institution (e.g., university) would host the workshop? Please also
comment on local research groups that would benefit from attracting
COMSOC.

**(3) Schedule.** What dates do you suggest? The workshop should take
place in or around May-September 2027. Are there any local
constraints? Are you aware of any other international events that may
affect the choice of dates (see partial list below)? What schedule do
you suggest for the paper reviewing procedure?

**(4) Budget.** How do you intend to finance the workshop? Please
provide a preliminary budget. Expenses to keep in mind include:
invited speakers, coffee breaks, lunches, a social dinner, and
possibly room and equipment hire, secretarial and administrative
support, and a half-day excursion. What level of registration (regular
and student) fees do you anticipate, and what would they cover? Please
ensure that fees are as low as possible.

Finally, please include any other issues you consider important.

All potential proposers are encouraged to contact us informally before
submitting a bid. Please do not hesitate to get in touch with any
questions, e.g., additional funding opportunities etc.
