Discrete Truthful Heterogeneous Two-Facility Location: The Line and Beyond
Panagiotis Kanellopoulos, Alexandros A. Voudouris
We study deterministic strategyproof mechanisms for discrete heterogeneous two-facility location. In our model, agents occupy distinct nodes of a connected graph and privately…
Distributed Agent-Constrained Truthful Facility Location
Argyrios Deligkas, Panagiotis Kanellopoulos, Alexandros A. Voudouris
We study a distributed facility location problem in which a set of agents, each with a private position on the real line, is partitioned into a collection of fixed, disjoint groups…
Truthful Facility Location with Candidate Locations and Limited Resources
Panagiotis Kanellopoulos, Alexandros A. Voudouris
We study a truthful facility location problem where one out of available facilities must be built at a location chosen from a set of candidate ones in the interval …
On Interim Envy-Free Allocation Lotteries
Ioannis Caragiannis, Panagiotis Kanellopoulos, Maria Kyropoulou
With very few exceptions, recent research in fair division has mostly focused on deterministic allocations. Deviating from this trend, we study the fairness notion of interim envy-…
Optimal Bailouts and Strategic Debt Forgiveness in Financial Networks
Panagiotis Kanellopoulos, Maria Kyropoulou, Hao Zhou
A financial system is represented by a network, where nodes correspond to banks, and directed labeled edges correspond to debt contracts between banks. Once a payment schedule has…
Constrained Truthful Obnoxious Two-Facility Location with Optional Preferences
Panagiotis Kanellopoulos, Alexandros A. Voudouris
We consider a truthful facility location problem with agents that have private positions on the line of real numbers and known optional preferences over two obnoxious facilities th…
