在一个布尔电路中计算布尔函数$f$的最小非门数称为$f \cdot$的求逆复杂度。1958年,马尔可夫确定了每个布尔函数的反演复杂度,并特别证明了$ \lceil\log_{2}(n+1)\rceil$ NOT门足以计算$n$个变量的任何布尔函数。在本文中,我们考虑电路的概率计算,并证明如果概率电路以概率$1/2+p$计算出正确值,并且对于某个常数$p >0$,则求逆复杂度的降低最多是一个常数。
The minimum number of NOT gates in a Boolean circuit computing a Boolean function $f$ is called the inversion complexity of $f \cdot$ . In 1958, Markov determined the inversion complexity of every Boolean function and particularly proved that $ \lceil\log_{2}(n+1)\rceil$ NOT gates are sufficient to compute any Boolean function on $n$ variables. In this note, we consider circuits computing probabilistically, and prove that the decrease of the inversion complexity is at most a constant if probabilistic circuits compute a correct value with probability $1/2+p$ for some constant $p >0$ .
