Allocating Indivisible Goods to Strategic Agents: Pure Nash Equilibria and Fairness

no code implementations17 Sep 2021 Georgios Amanatidis, Georgios Birmpas, Federico Fusco, Philip Lazos, Stefano Leonardi, Rebecca Reiffenhäuser

For Round-Robin we show that all of its pure Nash equilibria induce allocations that are EF1 with respect to the underlying true values, while for the algorithm of Plaut and Roughgarden we show that the corresponding allocations not only are EFX but also satisfy maximin share fairness, something that is not true for this algorithm in the non-strategic setting!

Submodular Maximization subject to a Knapsack Constraint: Combinatorial Algorithms with Near-optimal Adaptive Complexity

no code implementations16 Feb 2021 Georgios Amanatidis, Federico Fusco, Philip Lazos, Stefano Leonardi, Alberto Marchetti Spaccamela, Rebecca Reiffenhäuser

Submodular maximization is a classic algorithmic problem with multiple applications in data mining and machine learning; there, the growing need to deal with massive instances motivates the design of algorithms balancing the quality of the solution with applicability.

Trend Detection based Regret Minimization for Bandit Problems

no code implementations15 Sep 2017 Paresh Nakhe, Rebecca Reiffenhäuser

In this paper, we study this problem when the losses of the actions also satisfy certain structural properties, and especially, do show a trend structure.
