Fast Evaluation of Sequence Pair in Block Placement by Longest Common Subsequence Computation
In [1], Murata et al introduced an elegant representation of block placement called sequence pair. All block placement algorithms which are based on sequence pairs use simulated a...

Robust optimization of contaminant sensor placement for community water systems
We present a series of related robust optimization models for placing sensors in municipal water networks to detect contaminants that are maliciously or accidentally injected. We f...

Hardness and Approximation of the Survivable Multi-Level Fat Tree Problem
—With the explosive deployment of “triple play” (voice, video and data services) over the same access network, guaranteeing a certain-level of survivability for the access ne...

Approximating the Problem, not the Solution: An Alternative View of Point Set Matching
This work discusses the issue of approximation in point set matching problems. In general, one may have two classes of approximations when tackling a matching problem: a representa...

An Approximation Algorithm for Computing a Parsimonious First Speciation in the Gene Duplication Model
We consider the following problem: given a forest of gene family trees on a set of genomes, find a first speciation which splits these genomes into two subsets and minimizes the ...
