Complexity and Approximability of Parameterized CSP

open access: yes, 2016
The complexity of various Constraint Satisfaction Problems (CSP) when parameterized by structural measures (such as treewidth or clique-width) is a well-investigated area.

On the Parameterized Complexity of Contraction to Generalization of Trees [PDF]

open access: yes, 2018
For a family of graphs F, the F-Contraction problem takes as an input a graph G and an integer k, and the goal is to decide if there exists S \subseteq E(G) of size at most k such that G/S belongs to F.

Searching and Indexing Genomic Databases via Kernelization

open access: yesFrontiers in Bioengineering and Biotechnology, 2015
The rapid advance of DNA sequencing technologies has yielded databases of thousands of genomes. To search and index these databases effectively, it is important that we take advantage of the similarity between those genomes.

Parameterized Complexity of Binary CSP: Vertex Cover, Treedepth, and Related Parameters [PDF]

open access: yes, 2023
We investigate the parameterized complexity of Binary CSP parameterized by the vertex cover number and the treedepth of the constraint graph, as well as by a selection of related modulator-based parameters.

Crossing Numbers and Parameterized Complexity [PDF]

open access: yes, 2008
The odd crossing number of G is the smallest number of pairs of edges that cross an odd number of times in any drawing of G. We show that there always is a drawing realizing the odd crossing number of G that uses at most 9k crossings, where k is the odd crossing number of G.

The Parameterized Complexity of Degree Constrained Editing Problems [PDF]

open access: yes, 2009
This thesis examines degree constrained editing problems within the framework of parameterized complexity. A degree constrained editing problem takes as input a graph and a set of constraints and asks whether the graph can be altered in at most k editing

RNA inverse folding can be solved in linear time for structures without isolated stacks or base pairs

open access: yesAlgorithms for Molecular Biology
Inverse folding is a classic instance of negative RNA design which consists in finding a sequence that uniquely folds into a target secondary structure with respect to energy minimization. A breakthrough result of Bonnet et al. shows that, even in simple

Streaming Deletion Problems Parameterized by Vertex Cover [PDF]

open access: yes, 2021
Streaming is a model where an input graph is provided one edge at a time, instead of being able to inspect it at will. In this work, we take a parameterized approach by assuming a vertex cover of the graph is given, building on work of Bishnu et al ...
