The Interval Constrained 3-Coloring Problem
Abstract In this paper, we settle the open complexity status of interval constrained coloring with a fixed number of colors. We prove that the problem is already NP-complete if th...

Network delay inference from additive metrics
We demonstrate the use of computational phylogenetic techniques to solve a central problem in inferential network monitoring. More precisely, we design a novel algorithm for multi...

A Metric on the Space of Reduced Phylogenetic Networks
—Phylogenetic networks are leaf-labeled, rooted, acyclic, directed graphs, that are used to model reticulate evolutionary histories. Several measures for quantifying the topologi...

Towards practical feasibility of core computation in data exchange
Abstract. Core computation in data exchange is concerned with materializing the minimal target database for a given source database. Gottlob and Nash have recently shown that the c...

Learning Convex Concepts from Gaussian Distributions with PCA
We present a new algorithm for learning a convex set in n-dimensional space given labeled examples drawn from any Gaussian distribution. The complexity of the algorithm is bounded ...
