On implicational bases of closure system with unique critical sets

Adaricheva, Kira; Nation, J.B. (2013)

We show that every optimum basis of a nite closure system, in D. Maier's sense, is also right-side optimum, which is a parameter of a minimum CNF representation of a Horn Boolean function. New parameters for the size ...
