Parameterized and Exact Computation

TheInternationalSymposiumonParameterizedandExactComputation(IPEC, formerly IWPEC) is an international symposium series that covers research in all aspects of parameterized and exact algorithms and complexity. Started in 2004 as a biennial workshop, it became an annual event from 2008. The four previous meetings of the IPEC/IWPEC series were held in Bergen, Norway(2004),Zu rich,Switzerland(2006),Victoria,Canada(2008)andCop- hagen, Denmark (2009). On recommendations of the Steering Committee, from this year, the word symposium replaces the word workshop in the name, and it gets a new abbreviation IPEC (rhyming with the old one IWPEC). IPEC 2010 was the ?fth symposium in the series, held in Chennai, India, during December 13-15, 2010. The symposium was co-located with the 30th Foundations of Software Technology and Theoretical Computer Science conf- ence (FSTTCS 2010), a premier theory conference in India. At IPEC 2010, we had three plenary speakers: Anuj Dawar (University of Cambridge, UK), Fedor V. Fomin (University of Bergen, Norway) and Toby Walsh (NICTA and University of New South Wales, Australia).

Klappentext

This book constitutes the refereed best selected papers of the 5th International Symposium on Parameterized and Exact Computation, IPEC 2010, held in Chennai, India, in December 2010. The 19 revised full papers presented were carefully reviewed and selected from 32 submissions. The topics addressed cover research in all aspects of parameterized and exact computation and complexity, including but not limited to new techniques for the design and analysis of parameterized and exact algorithms; parameterized complexity theory; relationship between parameterized complexity and traditional complexity classifications; applications of parameterized and exact computation; implementation issues of parameterized and exact algorithms; fixed-parameter approximation; fast approximation in exponential time; kernelization lower and upper bounds.
