Allocation of Indivisible Items with a Common Preference Graph: Minimizing Total Dissatisfaction

Nina Chiarelli, Clément Dallard, Andreas Darmann +4

Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the i…

Minimizing Maximum Dissatisfaction in the Allocation of Indivisible Items under a Common Preference Graph

Nina Chiarelli, Clément Dallard, Andreas Darmann +4

We consider the task of allocating indivisible items to agents, when the agents' preferences over the items are identical. The preferences are captured by means of a directed acycl…

A linear time algorithm for linearizing quadratic and higher-order shortest path problems

Eranda Çela, Bettina Klinz, Stefan Lendl +2

An instance of the NP-hard Quadratic Shortest Path Problem (QSPP) is called linearizable iff it is equivalent to an instance of the classic Shortest Path Problem (SPP) on the same…

On the Complexity of Robust Multi-Stage Problems in the Polynomial Hierarchy

Marc Goerigk, Stefan Lendl, Lasse Wulf

We study the computational complexity of multi-stage robust optimization problems. Such problems are formulated with alternating min/max quantifiers and therefore naturally fall in…

Dispersing Obnoxious Facilities on Graphs by Rounding Distances

Tim A. Hartmann, Stefan Lendl

We continue the study of -dispersion, a continuous facility location problem on a graph where all edges have unit length and where the facilities may also be positioned in the i…

Allocation of Indivisible Items with Individual Preference Graphs

Nina Chiarelli, Clément Dallard, Andreas Darmann +5

This paper studies the allocation of indivisible items to agents, when each agent's preferences are expressed by means of a directed acyclic graph. The vertices of each preference…
