Exact and Parameterized Algorithms for Choosability
In the Choosability problem (or list chromatic number problem), for a given graph G, we need to find the smallest k such that G admits a list coloring for any list assignment where all lists contain at least k co...

Parameterized Algorithms for Covering by Arithmetic Progressions
An arithmetic progression is a sequence of integers in which the difference between any two consecutive elements is the same. We investigate the parameterized complexity of two problems related to arithmetic prog...

Parameterized Complexity of Paired Domination
The Paired Domination problem is one of the well-studied variants of the classical Dominating Set problem. In a graph G on n vertices, a dominating set D (set of vertices such that

Solving Target Set Selection with Bounded Thresholds Faster than \(2^n\)
In this paper we consider the Target Set Selection problem. The problem naturally arises in many fields like economy, sociology, medicine. In the Target Set Selection problem one is given a graph G with a functio...

Enumeration of Minimal Tropical Connected Sets
A subset of vertices in a vertex-colored graph is called tropical if vertices of each color present in the subset. This paper is dedicated to the enumeration of all minimal tropical connected sets in various c...

Fair Division with Minimal Withheld Information in Social Networks
We present a study of a few graph based problems motivated by fair allocation of resources in a social network. The central role in the paper is played by the following problem: What is the largest number of i...

Two Generalizations of Proper Coloring: Hardness and Approximability
We study two natural generalizations of q -Coloring. These problems can be seen as optimization problems and are mostly applied to graphs that are not properly colorable with q colors. One of them is known as Max...

Maximizing Happiness in Graphs of Bounded Clique-Width
Clique-width is one of the most important parameters that describes structural complexity of a graph. Probably, only treewidth is more studied graph width parameter. In this paper we study how clique-width inf...

Upper and Lower Bounds for Different Parameterizations of (n,3)-MAXSAT
In this paper, we consider the (n,3)-MAXSAT problem. The problem is a special case of the Maximum Satisfiability problem with an additional requirement that in input formula each variable appears at most three...
