Hitting and Covering Partially
d-Hitting Set and d-Set Cover are among the classical NP-hard problems. In this paper, we study variants of d-Hitting Set and d-Set Cover, which are called Partial d -Hitting Set (Partial

On the Complexity of Singly Connected Vertex Deletion
A digraph D is singly connected if for all ordered pairs of vertices \(u,v\in V(D)\) , there is at most one path in D

Parameterized Complexity of Conflict-Free Matchings and Paths
An input to a conflict-free variant of a classical problem \(\Gamma \)Γ, called Conflict-Free\(\Gamma \)Γ, consists of an instance I of \(\Gamma \)Γ coupled with a graph H, called the conflict graph. A solution t...

Circumventing Connectivity for Kernelization
Classical vertex subset problems demanding connectivity are of the following form: given an input graph G on n vertices and an integer k, find a set S of at most k vertices that satisfies a property and G[S] is c...

Odd Cycle Transversal in Mixed Graphs
An odd cycle transversal (oct, for short) in a graph is a set of vertices whose deletion will leave a graph without any odd cycles. The Odd Cycle Transversal (OCT) problem takes an undirected graph G and a non-ne...

A Polynomial Kernel for Bipartite Permutation Vertex Deletion
In a permutation graph, vertices represent the elements of a permutation, and edges represent pairs of elements that are reversed by the permutation. In the Permutation Vertex Deletion problem, given an undirecte...

Burn and Win
Given a graph G and an integer k, the Graph Burning problem asks whether the graph G can be burned in at most k rounds. Graph burning is a model for information spreading in a network, where we study how fast the...
