Finding approximate palindromes in strings
We introduce a novel de nition of approximate palindromes in strings, and provide an algorithm to nd all maximal approximate palindromes in a string with up to k errors. Our de ni...

Analysis of Approximation Algorithms for k-Set Cover Using Factor-Revealing Linear Programs
We present new combinatorial approximation algorithms for k-set cover. Previous approaches are based on extending the greedy algorithm by efficiently handling small sets. The new a...

Constructing basis functions from directed graphs for value function approximation
Basis functions derived from an undirected graph connecting nearby samples from a Markov decision process (MDP) have proven useful for approximating value functions. The success o...
