--- Scope ---

Two standard approaches to handle hard (typically NP-hard) optimization
problems are to develop approximation and parameterized algorithms. For the
former, the runtime should be polynomial in the input size, but the
computed solution may deviate from the optimum. For the latter, the optimum
solution should be computed, but any super-polynomial runtime should be
isolated to some parameter of the input. Some problems however are hard to
approximate on one hand, and on the other it is also hard to obtain
parameterized algorithms for some given parameter. In this case one may
still hope to obtain parameterized approximation algorithms, which combine
the two paradigms, i.e. the computed solution may deviate from the optimum
and the runtime should have super-polynomial dependence only in some given
parameter. Recently there has been a great deal of development in proving
the existence or non-existence of parameterized approximation algorithms,
and the aim of this workshop is to bring together active researchers of
this emerging field, so that they may share their results and insights.
