Enumerating all minimal hitting sets in polynomial total time
Consider a hypergraph (=set system) whose hyperedges are
subsets of a set with w elements. We show that the minimal hitting sets of
can be enumerated in polynomial total time .Comment: 8 page
Coupon collecting and transversals of hypergraphs
Analysis of AlgorithmsThe classic Coupon-Collector Problem (CCP) is generalized. Only basic probability theory is used. Centerpiece rather is an algorithm that efficiently counts all k-element transversals of a set system
