Envy-free Allocations with Individual Payments

Robert Bredereck, Eva Deltl, Tanmay Inamdar +2

When an envy-free allocation of indivisible goods does not exist, monetary transfers can restore envy-freeness. Existing work on fair division with subsidies, however, typically as…

Reaching Fairness by Reallocating Goods

Robert Bredereck, Eva Deltl, Tanmay Inamdar +3

Fair allocation of indivisible goods has largely been studied under the assumption that no prior allocation exists. Motivated by practical settings with pre-existing (and possibly…

Optimally Selecting Representative Agents from a Metric Space

Benjamin Cookson, Eva Deltl, Yeeseok Oh

This paper studies the problem of proportionally fair clustering, where the goal is to select ``centers'' from a metric space that fairly represent a set of agents who also lie…

The Influence of Agent Models on the Complexity of Bus Routing

Eva Deltl, Christian Komusiewicz, Jurek Rostalsky +2

In bus routing, the task is to plan a bus route in a network with several agents, each of whom wants to travel from a starting point to a destination. A bus route should account fo…

Improved Lower Bounds for Proportionally Fair Clustering

Benjamin Cookson, Eva Deltl, Yeeseok Oh

We study proportionally fair clustering, where a set of centers must be chosen from a metric space to represent agents, and no sufficiently large group of agents should be…

Minimizing the Cost of EFx Allocations

Eva Deltl

Ensuring fairness while limiting costs, such as transportation or storage, is an important challenge in resource allocation, yet most work has focused on cost minimization without…

The Core in Max-Loss Non-Centroid Clustering Can Be Empty

Robert Bredereck, Eva Deltl, Leon Kellerhals +1

We study core stability in non-centroid clustering under the max-loss objective, where each agent's loss is the maximum distance to other members of their cluster. We prove that fo…

How to Resolve Envy by Adding Goods

Matthias Bentert, Robert Bredereck, Eva Deltl +2

We consider the problem of resolving the envy of a given initial allocation by adding elements from a pool of goods. We give a characterization of the instances where envy can be r…

Algorithmics of Egalitarian versus Equitable Sequences of Committees

Eva Michelle Deltl, Till Fluschnik, Robert Bredereck

We study the election of sequences of committees, where in each of levels (e.g. modeling points in time) a committee consisting of candidates from a common set of candi…
