Analysis of bounds for a capacitated single-item lot-sizing problem
Lot-sizing problems are cornerstone optimization problems for production planning with time varying demand. We analyze the quality of bounds, both lower and upper, provided by a r...

Topological Persistence and Simplification
We formalize a notion of topological simplification within the framework of a filtration, which is the history of a growing complex. We classify a topological change that happens ...

Computing Linking Numbers of a Filtration
We develop fast algorithms for computing the linking number of a simplicial complex within a ļ¬ltration. We give experimental results in applying our work toward the detection of...

Straightening Drawings of Clustered Hierarchical Graphs
In this paper we deal with making drawings of clustered hierarchical graphs nicer. Given a planar graph G = (V, E) with an assignment of the vertices to horizontal layers, a plane ...

Distortion-Complexity Optimization of the H.264/MPEG-4 AVC Encoder using the GBFOS Algorithm
The H.264/ACV standard provides significant improvements in performance over earlier video coding standards at the cost of increased complexity. Our challenge is to determine H.26...
