Differentiable Combinatorial Auction Design: Optimizing Revenue-Welfare-Fairness Frontiers With Graph Attention Networks
Mai Pham, Vikrant Vaze, Peter Chin
Designing optimal auctions for allocating public infrastructure-such as airport slots and energy resources-is challenging due to interdependent resources and complex side-constrain…

L2R-EV: Learning What to Repair in Electric Ride-Pooling with Finite Charger Queues
Mai Pham, Vikrant S. Vaze, Peter Chin
Electric ride-pooling must jointly manage passenger service, routes, batteries, and finite chargers; a locally useful relocation can reduce later service. We introduce a discrete-e…

Advancing Differentiable Economics: A Neural Network Framework for Revenue-Maximizing Combinatorial Auction Mechanisms
Mai Pham, Vikrant Vaze, Peter Chin
Differentiable economics, which uses neural networks as function approximators and gradient-based optimization in automated mechanism design (AMD), marked a significant breakthroug…
