Minimum Distance Localization for a Robot with Limited Visibility
— Minimum distance localization is the problem of finding the shortest possible path for a robot to eliminate ambiguity regarding its position in the environment. We consider th...

Clustering for metric and non-metric distance measures
We study a generalization of the k-median problem with respect to an arbitrary dissimilarity measure D. Given a finite set P, our goal is to find a set C of size k such that the s...

Bit-parallel string matching under Hamming distance in O(n[m/w]) worst case time
Given two strings, a pattern P of length m and a text T of length n over some alphabet , we consider the string matching problem under k mismatches. The well

Reversal Distance for Strings with Duplicates: Linear Time Approximation using Hitting Set
In the last decade there has been an ongoing interest in string comparison problems; to a large extend the interest was stimulated by genome rearrangement problems in computationa...

On earthmover distance, metric labeling, and 0-extension
We study the fundamental classification problems 0-Extension and Metric Labeling. A generalization of Multiway Cut, 0-Extension is closely related to partitioning problems in grap...
