On Revenue Maximization in Second-Price Ad Auctions
Most recent papers addressing the algorithmic problem of allocating advertisement space for keywords in sponsored search auctions assume that pricing is done via a first-price auction, which does not realistic...

Improved Approximation Algorithms for Budgeted Allocations
We provide a 3/2-approximation algorithm for an offline budgeted allocations problem with applications to sponsored search auctions. This an improvement over the e/(e − 1) approximation of Andelman and Mansour [1...

Truthful and Competitive Double Auctions
In this paper we consider the problem of designing a mechanism for double auctions where bidders each bid to buy or sell one unit of a single commodity. We assume that each bidder’s utility value for the item ...

Web Search via Hub Synthesis
We present a probabilistic generative model for web search which captures in a unified manner three critical components of web search: how the link structure of the web is generated, how the content of a web d...

An Experimental Study of Data Migration Algorithms
The data migration problem is the problem of computing a plan for moving data objects stored on devices in a network from one configuration to another. Load balancing or changing usage patterns might necessitate ...

On List Update and Work Function Algorithms
The list update problem, a well-studied problem in dynamic data structures, can be described abstractly as a metrical task system. In this paper, we prove that a generic metrical task system algorithm, called the...
