Add to ORKGAbstract. Combining classical approximability questions with parameterized complexity, we introduce a theory of parameterized approximability. The main intention of this theory is to deal with the efficient approximation of small cost solutions for optimisation problems. Key words. Fixed-parameter tractability, approximation algorithms, hardness of approximation.
