Improved approximation algorithms for low-density instances of the Minimum Entropy Set Cover Problem

Cosmin Bonchis, Gabriel Istrate

We study the approximability of instances of the minimum entropy set cover problem, parameterized by the average frequency of a random element in the covering sets. We analyze an a…
