Deterministic Stackelberg Strategies in Robotaxi Assignment Games
Ioannis Caragiannis, Kostas Kollias, Mohammad Roghani +2
In autonomous mobility duopolies, platforms compete for riders based on vehicle proximity. A critical operational challenge---faced by an incumbent proactively defending against a…
A Unified Framework for Uniform-Price Resource Allocation Mechanisms
Ioannis Caragiannis, Dimitris Fotakis, Stratis Skoulakis
Mechanisms for allocating a divisible resource among strategic agents have been widely studied. The prominent paradigm is the proportional (Kelly) mechanism, which elicits a scalar…
The Robotaxi Placement Problem: Minimizing Expected ETA for Stochastic Demand
Ioannis Caragiannis, Kostas Kollias, Mohammad Roghani +2
Autonomous ride-hailing platforms must strategically position idle robotaxis to minimize the wait times of prospective riders. We formalize this as the robotaxi placement problem (…
The Distortion of Prior-Independent b-Matching Mechanisms
Ioannis Caragiannis, Vasilis Gkatzelis, Sebastian Homrighausen
In a setting where items need to be partitioned among agents, we evaluate the performance of mechanisms that take as input each agent's \emph{ordinal preferences}, i.e., th…
