Parameterized Complexity of Connected Network Microaggregation: The Role of Cluster Size

Ajinkya Gaikwad, Dušan Knop, Tomáš Valla

Network microaggregation is a fundamental technique in statistical disclosure control, where vertices of a graph are partitioned into clusters satisfying size constraints and admit…

Parameterized Complexity of Edge-Constrained Graph Partitioning

Ajinkya Gaikwad, Jan Pokorný, Tomáš Valla

We study the Edge-Constrained Graph Partitioning Problem (ECGP), which asks whether the vertices of a graph can be partitioned into r parts, each inducing at least gamma edges. We…

Computing m-Eternal Domination Number of Cactus Graphs in Linear Time

Václav Blažej, Jan Matyáš Křišťan, Tomáš Valla

In m-eternal domination attacker and defender play on a graph. Initially, the defender places guards on vertices. In each round, the attacker chooses a vertex to attack. Then, the…

On Polynomial Kernels for Traveling Salesperson Problem and its Generalizations

Václav Blažej, Pratibha Choudhary, Dušan Knop +3

For many problems, the important instances from practice possess certain structure that one should reflect in the design of specific algorithms. As data reduction is an important a…

Efficient attack sequences in m-eternal domination

Václav Blažej, Jan Matyáš Křišťan, Tomáš Valla

We study the m-eternal domination problem from the perspective of the attacker. For many graph classes, the minimum required number of guards to defend eternally is known. By defin…

Polynomial Kernels for Tracking Shortest Paths

Václav Blažej, Pratibha Choudhary, Dušan Knop +3

Given an undirected graph , vertices , and an integer , Tracking Shortest Paths requires deciding whether there exists a set of vertices su…
