Approximation Algorithms for the Max-Min Allocation Problemproximation algorithm for Max-Min when there are . people with subadditive utility functions. We also give a ./.-approximation algorithm (for . ≤ ./2) if the utility functions are additive and the utility of an item for a person is restricted to 0, 1 or . for some . > 1. The running time of this alg

Maximum Gradient Embeddings and Monotone Clustering . ∈ ., . where . is a universal constant. Conversely we show that the above quadratic dependence on log. cannot be improved in general. Such embeddings, which we call ., yield a framework for the design of approximation algorithms for a wide range of clustering problems with monotone costs, includi

Such situations arise in many contexts, e.g., hiring workers, scheduling jobs, and bidding in sponsored search auctions..This problem, often called the ., is known to be inapproximable. Therefore, we make the enabling assumption that elements arri

Our linear programing rounding algorithm is the first one that touches the approximability limit curve . established by Jain et al. As a consequence, we obtain the first optimal approximation algorithm for instances domi
