Parameterized complexity theory
WebAug 11, 2024 · In this paper we argue that the framework of parameterized complexity has a lot to offer for the complexity analysis of description logic reasoning problems---when one takes a progressive and forward-looking view on parameterized complexity tools. We substantiate our argument by means of three case studies. WebIn computer science, parameterized complexity is a measure of complexity of problems with multiple input parameters. The theory of parameterized complexity was developed in …

In computer science, parameterized complexity is a branch of computational complexity theory that focuses on classifying computational problems according to their inherent difficulty with respect to multiple parameters of the input or output. The complexity of a problem is then measured as a function of those … See more FPT FPT contains the fixed parameter tractable problems, which are those that can be solved in time $${\displaystyle f(k)\cdot { x }^{O(1)}}$$ for some computable function f. Typically, … See more • Wiki on parameterized complexity • Compendium of Parameterized Problems See more • Parameterized approximation algorithm, for optimization problems an algorithm running in FPT time might approximate the solution.

WebApproximation algorithms and parameterized complexity are usually considered to be two separate ways of dealing with hard algorithmic problems. In this paper, our aim is to investigate how these two fields can be combined to achieve better algorithms than what any of the two theories could offer.
