Approximation Algorithms for Partial Covering Problemsty at most three, we obtain an approximation of 4/3. We also present better-than-2-approximation algorithms for .-vertex cover on bounded degree graphs, and for vertex cover on expanders of bounded . degree. We obtain a polynomial-time approximation scheme for .-vertex cover on planar graphs, and for covering points in .. by disks.

Then, we give an optimal method to construct a compact graph to represent the set of global roundings satisfying a weaker discrepancy condition.
