Mesh Collapse Compression
We present a novel algorithm for encoding the topology of triangular meshes. A sequence of edge contract and divide operations collapses the entire mesh into a single vertex. This ...

Stability of a frame-based oldest-cell-first maximal weight matching algorithm
Abstract-- Input-queued cell switches employing the oldestcell-first (OCF) policy have been shown to yield low mean delay characteristics. Moreover, it has been proven that OCF is ...

Decision Diagrams in Machine Learning: An Empirical Study on Real-Life Credit-Risk Data
Decision trees are a widely used knowledge representation in machine learning. However, one of their main drawbacks is the inherent replication of isomorphic subtrees, as a result...

A Tight Lower Bound for the Steiner Point Removal Problem on Trees
Gupta (SODA'01) considered the Steiner Point Removal (SPR) problem on trees. Given an edge-weighted tree T and a subset S of vertices called terminals in the tree, find an edg...
