Ergodic Theory and Related Topics IIIproblem; we feel that this idea may have wider implications. Our algorithm is conceptually simpler than the previous such cost-sharing method due to Pál and Tardos (., pages 584–593, 2003), and has a much improved approximation factor of 4.6 (over the previously known factor of 15).

https://doi.org/10.1007/978-3-319-74908-23]. We give an .(log.) approximation for this problem by using Garg .’s [10] algorithm for the multi-cut problem as a subroutine. Our algorithm also gives an .(log..) approximation for the .. norm of the additive distortion.

The Greedy Algorithm for the Minimum Common String Partition Problemut string, is NP-hard. We study a greedy algorithm for . that at each step extracts a longest common substring from the given strings. We show that the approximation ratio of this algorithm is between Ω(..) and .(..). In case of 2-., we show that the approximation ratio is equal to 3. For 4-., we give a lower bound of Ω(log .).

Peculiar submeasures on finite algebras, question by giving an algorithm for separable, differentiable, concave utility functions satisfying gross substitutes. Our algorithm uses the auction based approach of [10]..We also outline an extension of our method to the Walrasian model.
