Extracting Minimal and Closed Monotone DNF Formulas
Abstract. In this paper, first we introduce minimal and closed monotone DNF formulas as extensions of maximal and closed itemsets. Next, by incorporating the algorithm dnf cover d...

Tight Results on Minimum Entropy Set Cover
In the minimum entropy set cover problem, one is given a collection of k sets which collectively cover an n-element ground set. A feasible solution of the problem is a partition o...

On the Impact of Local Taxes in a Set Cover Game
Given a collection C of weighted subsets of a ground set E, the set cover problem is to find a minimum weight subset of C which covers all elements of E. We study a strategic game ...

An Approximation Algorithm for the Minimum Latency Set Cover Problem
The input to the minimum latency set cover problem (MLSC) consists of a set of jobs and a set of tools. Each job j needs a specific subset Sj of the tools in order to be processed...

Sequential covering rule induction algorithm for variable consistency rough set approaches
We present a general rule induction algorithm based on sequential covering, suitable for variable consistency rough set approaches. This algorithm, called VC-DomLEM, can be used f...
