Generating k-best solutions to auction winner determination problems

Terence Kelly, Andrew Byde
2006 ACM SIGecom Exchanges  
The WDP in sealed-bid CAs is a generalized knapsack problem [Kelly 2004]. 2. Dynamic programming can solve such problems [Kellerer et al. 2004]. 3.  ...  Bids may express volume discounts/surcharges, and multi-sourcing is supported. The k-cheapest solutions to a procurement auction can be post-processed in several ways to aid the decision-maker.  ...  Finally, we thank the anonymous SIGecom Exchanges reviewers for their detailed comments.  ...

Segmenting two-sided markets

Siddhartha Banerjee, Sreenivas Gollapudi, Kostas Kollias, Kamesh Munagala
2017 ACM SIGecom Exchanges  
We develop efficient algorithms for throughput (i.e. volume of trade) and welfare maximization with provable guarantees under a variety of assumptions on the demand and supply functions.  ...  Now consider a single pooled market with total demand volume d = K k=1 d k and total supply volume s = K k=1 s k .  ...  Define r(x) = F (p(x)), where p(x) is the solution to xH(p) = F (p) -in other words, r(x) is throughput with unit supply volume and demand volume x.  ...
