Lower estimates of circuit complexity in the basis of antichain functions
Olga Podolskaya · Moscow University Mathematics Bulletin · 2013
The antichain function is a characteristic function of an antichain in the Boolean cube. The set of antichain functions is an infinite complete basis. We study the computational complexity of Boolean functions over an antichain functional basis. In this paper we prove an asymptotic lower bound of order $\sqrt n $ for the computational complexity of a linear function, a majority function, and almost all Boolean functions of n variables.
