Constrained Energy Minimization for Matching-Based Image Recognition
We propose to use energy minimization in MRFs for matching-based image recognition tasks. To this end, the Tree-Reweighted Message Passing algorithm is modified by geometric cons...

Exact and Approximation Algorithms for DNA Tag Set Design
In this paper we propose new solution methods for designing tag sets for use in universal DNA arrays. First, we give integer linear programming formulations for two previous formal...

A Greedy Algorithm for Capacity-Constrained Surrogate Placement in CDNs
One major factor that heavily affects the performance of a content distribution network (CDN) is placement of the surrogates. Previous works take a network-centric approach and con...

Parallel Query Processing and Edge Ranking of Graphs
Abstract. In this paper we deal with the problem of finding an optimal query execution plan in database systems. We improve the analysis of a polynomial-time approximation algorit...
