Parameterized Complexity of 1-Planarity [PDF]
We consider the problem of drawing graphs with at most one crossing per edge. These drawings, and the graphs that can be drawn in this way, are called $1$-planar. Finding $1$-planar drawings is known to be ${\mathsf{NP}}$-hard, but we prove that it is fixed-parameter tractable with respect to the vertex cover number, tree-depth, and cyclomatic number ...

Parameterized Complexity of Graph Burning
AbstractGraph Burning asks, given a graph $$G = (V,E)$$ G = ( V , E ) and an integer k, whether there exists $$(b_{0},\dots ,b_{k-1}) \in V^{k}$$

Completeness Results for Parameterized Space Classes
The parameterized complexity of a problem is considered "settled" once it has been shown to lie in FPT or to be complete for a class in the W-hierarchy or a similar parameterized hierarchy.

On the Average-case Complexity of Parameterized Clique [PDF]
The k-Clique problem is a fundamental combinatorial problem that plays a prominent role in classical as well as in parameterized complexity theory. It is among the most well-known NP-complete and W[1]-complete problems.

Parameterized Complexity of Safe Set [PDF]
In this paper we study the problem of finding a small safe set $S$ in a graph $G$, i.e., a non-empty set of vertices such that no connected component of $G[S]$ is adjacent to a larger component in $G - S$. We enhance our understanding of the problem from the viewpoint of parameterized complexity by showing that (1) the problem is W[2]-hard when ...

The Parameterized Complexity of Graph Cyclability [PDF]
The cyclability of a graph is the maximum integer $k$ for which every $k$ vertices lie on a cycle. The algorithmic version of the problem, given a graph $G$ and a non-negative integer $k,$ decide whether the cyclability of $G$ is at least $k,$ is {\sf NP}-hard. We study the parametrized complexity of this problem.

Parameterized bounded-depth Frege is not optimal [PDF]
A general framework for parameterized proof complexity was introduced by Dantchev, Martin, and Szeider [9]. There the authors concentrate on tree-like Parameterized Resolution-a parameterized version of classical Resolution-and their gap complexity ...

We suggest a user-oriented approach to combinatorial data anonymization. A data matrix is called k-anonymous if every row appears at least k times—the goal of the NP-hard k-ANONYMITY problem then is to make a given matrix k-anonymous by suppressing ...

A LCCR filter based harmonic suppression method for power quality improvement
As power converters have been widely used in renewable energy generation and motor drive system for the industrial production, the harmonics of output voltage of power converter will seriously affect the system power quality.
