| heal.abstract | For any epsilon > 0 we give a (2 + epsilon)-approximation algorithm for the problem of finding a minimum tree spanning any k vertices in a graph (k-MST), improving a 3-approximation algorithm by Garg [10]. As in [10] the algorithm extends to a (2 + epsilon)-approximation algorithm for the minimum tour that visits any k vertices, provided the edge costs satisfy the triangle inequality. | en |
