Parameterized complexity theory
WebThe embedding problem is to decide, given an ordered pair of structures, whether or not there is an injective homomorphism from the first structure to the second. We study this problem using an established perspective in parameterized complexity theory: ... WebFor two integers r, ℓ ź 0, a graph G = (V, E) is an (r, ℓ)-graph if V can be partitioned into r independent sets and ℓ cliques. In the parameterized (r, ℓ)-Vertex Deletion problem, given a graph G and an integer k, one has to decide whether at most k ...

WebIn computer science, parameterized complexity is a measure of complexity of problems with multiple input parameters. The theory of parameterized complexity was developed in … 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.
