Lower bounds on the DNF exception problem for short exception lists and related problems

Abstract

In this paper we prowide lower bounds on the complexity of the DNF exception problem for short exception lists and hypercube covering problem. The method proposed is based on the relaxation of the initial problem to a certain linear programming problem. Some explicit bounds are provided for the case when exception list size is bounded above by a logarithm of dimension. The bound provided in this case is significantly stronger than the bounds known before.
