Finding Small Multi-Demand Set Covers with Ubiquitous Elements and Large Sets is Fixed-Parameter Tractable

Niclas Boehmer, Robert Bredereck, Dušan Knop +1

We study a variant of Set Cover where each element of the universe has some demand that determines how many times the element needs to be covered. Moreover, we examine two generali…

A Fast Exact Algorithm for Airplane Refueling Problem

Jianshu Li, Xiaoyin Hu, Junjie Luo +1

We consider the airplane refueling problem, where we have a fleet of airplanes that can refuel each other. Each airplane is characterized by specific fuel tank volume and fuel cons…

Adapting Stable Matchings to Evolving Preferences

Robert Bredereck, Jiehua Chen, Dušan Knop +2

Adaptivity to changing environments and constraints is key to success in modern society. We address this by proposing "incrementalized versions" of Stable Marriage and Stable Roomm…

Parameterized Dynamic Cluster Editing

Junjie Luo, Hendrik Molter, André Nichterlein +1

We introduce a dynamic version of the NP-hard graph problem Cluster Editing. The essential point here is to take into account dynamically evolving input graphs: Having a cluster gr…

A Parameterized Complexity View on Collapsing k-Cores

Junjie Luo, Hendrik Molter, Ondrej Suchy

We study the NP-hard graph problem Collapsed k-Core where, given an undirected graph G and integers b, x, and k, we are asked to remove b vertices such that the k-core of remaining…
