Task 7: Logics, games, and efficient query evaluation
Objectives
Game-theoretic techniques will be used to attack unresolved problems of expressiveness, such as fixed point hierarchies and the associated algorithmic questions. Model checking games will be used for efficient formula evaluation with applications to verification and query evaluation. The network will develop algorithms and perform systematic complexity and scalability studies for query evaluation, concentrating on structural properties of data that have been shown to significantly reduce query complexity.
