Ubiquitous Parameterization - Invitation to Fixed-Parameter Algorithms
Abstract. Problem parameters are ubiquitous. In every area of computer science, we find all kinds of “special aspects” to the problems encountered. Hence, the study of paramet...

LWPP and WPP are not uniformly gap-definable
Resolving an issue open since Fenner, Fortnow, and Kurtz raised it in [FFK94], we prove that LWPP is not uniformly gap-definable and that WPP is not uniformly gap-definable. We do...

A Structural View on Parameterizing Problems: Distance from Triviality
Based on a series of known and new examples, we propose the generalized setting of “distance from triviality” measurement as a reasonable and prospective way of determining use...
