33rd ACM Symposium on Theory of Computing (STOC)
作者: Goemans, MX Williamson, DP IBM Almaden San Jose CA 95120 USA MIT Cambridge MA 02139 USA
A number of recent papers on approximation algorithms have used the square roots of unity, -1 and 1, to represent binary decision variables for problems in combinatorial optimization, and have relaxed these to unit ve... 详细信息

18th ACM-SIAM Symposium on Discrete algorithms
作者: Srinivasan, Aravind Univ Maryland Dept Comp Sci College Pk MD 20742 USA
We present improved approximation algorithms in stochastic optimization. We prove that the multi-stage stochastic versions of covering integer programs (such as set cover and vertex cover) admit essentially the same a... 详细信息

35th International Conference on Machine Learning (ICML)
作者: Streeter, Matthew Google Res Mountain View CA 94043 USA
We present an approximation algorithm that takes a pool of pre-trained models as input and produces from it a cascaded model with similar accuracy but lower average-case cost. Applied to state-of-the-art ImageNet clas... 详细信息

15th International Conference on Integer Programming and Combinatorial Optimization (IPCO)
作者: Grandoni, Fabrizio Rothvoss, Thomas Univ Roma Tor Vergata Rome Italy MIT Cambridge MA 02139 USA
In the classical facility location problem we are given a set of facilities, with associated opening costs, and a set of clients. The goal is to open a subset of facilities, and to connect each client to the closest o... 详细信息

10th Annual International Symposium on algorithms and Computation (ISAAC 99)
作者: Janssen, J Narayanan, L Dalhousie Univ Dept Math & Stat Halifax NS B3H 3J5 Canada Concordia Univ Dept Comp Sci Montreal PQ H3G 1M8 Canada
Cellular networks are generally modeled as node-weighted graphs, where the nodes represent cells and the edges represent the possibility of radio interference. An algorithm for the channel assignment problem must assi... 详细信息

13th Annual International Symposium on algorithms and Computation (ISAAC 2002)
作者: Arvind, V Raman, V Inst Math Sci Madras 600113 Tamil Nadu India
We give a randomized fixed parameter tractable algorithm to approximately count the number of copies of a k-vertex graph with bounded treewidth in an n vertex graph. As a consequence, we get randomized algorithms with... 详细信息

6th International Conference on Integer Programming and Combinatorial Optimization (IPCO VI)
作者: Raghavachari, B Veerasamy, J Univ Texas Comp Sci Program Richardson TX 75083 USA
The mixed postman problem, a generalization of the Chinese postman problem, is that of finding a shortest tour that traverses each edge of a given mixed graph (a graph containing both undirected and directed edges) at... 详细信息

20th International Conference on Computing and Combinatorics (COCOON)
作者: Shi, Feng Chen, Jianer Feng, Qilong Wang, Jianxin Cent S Univ Sch Informat Sci & Engn Changsha Hunan Peoples R China
Given a collection of phylogenetic trees with identical leaf label-set, the Maximum Agreement Forest problem (maf) asks for a largest common subforest of these input trees. The maf problem on two binary phylogenetic t... 详细信息
