We prove that the Minimum Equivalent DNF problem is S P 2 -complete, resolving a conjecture due to Stockmeyer. We also consider the complexity and approximability of a related optimization problem in the second level of the polynomial hierarchy, that of finding shortest implicants of a Boolean funct

✦ Synopsis
The minimum covering problem in weighted graphs with n vertices is transformed in time O(n 2) to the maximum matching problem with n or n + 1 vertices, and conversely.

A dual type algorithm constructs the minimum covering ball of a given finite set of points in R n by finding the minimum covering balls of a sequence of subsets, each with no more than n + 1 points and with strictly increasing radius, until all points are covered.
