On the problem of minimizing a single set of Boolean functions
Abstract:
We study the set of Boolean functions that consist of a single connected component, have minimal complexes of faces which are not shortest and do not satisfy the sufficient condition for minimality based on the notion of an independent set of vertices. The independent minimization for the connected components and feasibility of sufficient conditions for the minimality can not be applied to minimizing of such functions. For this set of functions, we obtain lower bounds on the power and maximal number of complexes of faces which are minimal with respect to additive measures of linear and polynomial complexity.
