IPEC

The International Symposium on Parameterized and Exact Computation (IPEC, formerly IWPEC) is a strongly peer-reviewed annual conference that covers research in all aspects of parameterized and exact algorithms and complexity.

History

The first International Workshop on Exact and Parameterized Computation (IWPEC) took place in Bergen in 2004. Since 2008, IWPEC has been held annually. In 2010, IWPEC changed its name to International Symposium on Parameterized and Exact Computation (IPEC). Since 2011, IPEC has often been co-located with the European Symposium on Algorithms (ESA) and other conference and workshops in the ALGO confederated conference, held in Europe in early September. The research contributions accepted for presentation at the conference appear in printed proceedings; the 2004–2014 conferences were published with Springer in the Lecture Notes in Computer Science series. Since 2015, the IPEC proceedings are published in the Leibniz International Proceedings in Informatics.

Steering Committee

Organization of the steering committee
Membership:
• for three years, rotates in September after IPEC
• the two PC chairs of IPEC x+1 join SC after IPEC x
• one additional member is elected by SC each year
• thus SC consists of nine members

How to join:
•Express interest in being an IPEC PC chair or SC member
• ultimately the SC decides by nomination plus vote
• soft tradition of being PC chair only once, so afterwards can only join the SC through vote
