Correlation clustering in general weighted graphs

E. Demaine, Dotan Emanuel, A. Fiat, Nicole Immorlica
Computer Science, Mathematics
Theor. Comput. Sci.
1 September 2006

We give an O(log n)-approximation algorithm for the general case based on a linear-programming rounding and the "region-growing" technique. Expand

Matroids, secretary problems, and online mechanisms

Moshe Babaioff, Nicole Immorlica, Robert D. Kleinberg
Mathematics, Computer Science
SODA '07
7 January 2007

We study a generalization of the classical secretary problem which we call the "matroid secretary problem". Expand

A Knapsack Secretary Problem with Applications

Mathematics, Computer Science
APPROX-RANDOM
20 August 2007

We consider situations in which a decision-maker with a fixed budget faces a sequence of options, each with a cost and a value, and must select a subset of them online so as to maximize the total value. Expand

A Simple and Approximately Optimal Mechanism for an Additive Buyer

Moshe Babaioff, Nicole Immorlica, B. Lucier, S. Weinberg

IEEE 55th Annual Symposium on Foundations of…
23 May 2014

We consider a monopolist seller with n heterogeneous items, facing a single buyer. Expand

Marriage, honesty, and stability

Nicole Immorlica, Mohammad Mahdian
Computer Science
SODA '05
23 January 2005

We show that, with high probability, the truthful strategy is the best response for a given player when the other players are truthful. Expand

Limitations of cross-monotonic cost sharing schemes

Nicole Immorlica, Mohammad Mahdian, V. Mirrokni
Mathematics, Computer Science
SODA '05
23 January 2005

A cost sharing scheme is a set of rules defining how to share the cost of a service (often computed by solving a combinatorial optimization problem) amongst serviced customers. Expand

Steve Chien, Nicole Immorlica
Computer Science
WWW '05
10 May 2005

We investigate the idea of finding semantically related search engine queries based on their temporal correlation; in other words, we infer that two queries are related if their popularities behave similarly over time. Expand

Coordination mechanisms for selfish scheduling

Nicole Immorlica, Erran L. Li, V. Mirrokni, Andreas S. Schulz
Computer Science
Theor. Comput. Sci.
1 December 2008

We study coordination mechanisms for four classes of multiprocessor machine scheduling problems and derive upper and lower bounds on the price of anarchy of these mechanisms. Expand

Dynamics of bid optimization in online advertisement auctions

C. Borgs, J. Chayes, Nicole Immorlica, K. Jain, O. Etesami, Mohammad Mahdian
Computer Science
WWW '07
8 May 2007

We consider the problem of online keyword advertising auctions among multiple bidders with limited budgets, and study a natural bidding heuristic in which advertisers attempt to optimize their utility by equalizing their return-on-investment across all keywords. Expand
