On the Parameterized Complexity of Bounded-Density Vertex Deletion
Jakob Raupach, Tom-Lukas Breitkopf, Anton Herrmann +1
We explore the parameterized complexity of Bounded Density Vertex Deletion (BDVD): given a graph , an integer budget , and a target density , the task is to determine…
Ranking Opinions with Few States in Population Protocols
Tom-Lukas Breitkopf, Julien Dallot, Antoine El-Hayek +1
Population protocols are a model of distributed computing where agents, each a simple finite-state machine, interact in pairs to solve a common task against a (adversarial) int…
Parameterized Algorithms for Computing MAD Trees
Tom-Lukas Breitkopf, Vincent Froese, Anton Herrmann +2
We consider the well-studied problem of finding a spanning tree with minimum average distance between vertex pairs (called a MAD tree). This is a classic network design problem whi…
Density Matters: A Complexity Dichotomy of Deleting Edges to Bound Subgraph Density
Matthias Bentert, Tom-Lukas Breitkopf, Vincent Froese +2
We study -Bounded-Density Edge Deletion (-BDED), where given an undirected graph , the task is to remove as few edges as possible to obtain a graph where no subgrap…
