A detailed program is now available. All the events are going to be held at the Wu and Chen Auditorium.

Please use this link to register for the conference. The registration fees are listed below. They include the opening reception, coffee breaks, and light breakfast.

The early registration deadline is June 26.

The registration information is used by the conference organizers to facilitate communication of registration confirmation and conference details, and for planning and running the event. Name, email address, status, and affiliation are shared with the executive committee of the Computational Complexity Foundation (CCF). Name and email address are used to determine the electorate for the CCF Board elections and for generating the ballots. Status and affiliation are used for statistics about conference attendance. Individual records are kept for no more than four years. Statistical data are kept indefinitely.

July is peak travel season in Philadelphia, and hotel accommodation may be difficult to find. For the convenience of the conference attendees, we have arranged for a block of rooms at The Study at a special rate of $192.00 + taxes. In return, the hotel expects that a significant fraction of the rooms will be booked. We encourage participants to book accommodations at The Study so that we can avoid the associated financial penalty.

The block covers the nights of July 20, 21, 22, and 23rd. The special rate is only for a limited number of rooms. To avail of this rate, call the hotel at (215) 387-1400 and ask for the rate for "Computational Complexity Conference". You may also use this link for booking the hotel at the group rate (valid until July 5).

In order to defray the costs of attending the conference, U.S. students may apply for travel allowances. Please see the application form for more details, and submit your application by the stated deadline for full consideration.

A visa to the US may be needed for attending the conference. This website has the exact rules. If a visa is needed, please get in touch with your local US consulate as soon as possible; the whole process may take several months. If you need an invitation letter, please email the local arrangements chair with the subject line "Visa request: CCC 2022".

The open exchange of ideas and the freedom of thought and expression are central to the aims and goals of CCC. These require an environment that recognizes the inherent worth of every person and group, that fosters dignity, understanding, and mutual respect, and that embraces diversity. The CCC'22 organizers are committed to providing an environment that is free of discrimination and harassment, and expect all participants to honor that commitment.

The CCF board extensively discussed the issue of allowing papers from scientists affiliated with Russia in the CCC program. Allowing them was not an easy decision, but it is one we feel is aligned with CCF's principles. We condemn the Russian Federation's war on Ukraine in the strongest possible terms. Our inclusion of some papers with Russian-affiliated authors is in no way to be construed as an endorsement of the Russian government or its actions.
