Combinatorial Auction

Combinatorial auctions are mechanisms for allocating multiple, indivisible items to bidders who can place bids on bundles of items, aiming to maximize overall welfare or revenue. Current research focuses on developing efficient algorithms and mechanisms, particularly for online settings with limited information about bidder valuations, employing techniques like reinforcement learning, Bayesian optimization, and graph neural networks to handle the computational complexity of large-scale auctions. These advancements are crucial for improving the design and implementation of auctions in diverse applications, such as environmental resource management, spectrum allocation, and energy markets, leading to more efficient and fair resource allocation.
