电路复杂性的模式基方法

The Pattern Basis Approach to Circuit Complexity

Bruce K. Smith

摘要:

我们描述和激励一个新的方法来下界的电路复杂性的布尔函数,基于一个新的形式化的“模式”作为一个特殊的基础上的所有真值表属性的向量空间的元素。我们证明了一个具有一定性质的“模式基”将导致一个有用的复杂性公式的特定形式,并推测如何找到这样的基础。这个公式在任意函数上的计算时间可能与在电路中进行蛮力搜索的时间一样长,从而解决了自然证明的障碍,但它的形式适合于证明易于理解的显式函数的下界。

英文摘要:

We describe and motivate a proposed new approach to lowerbounding the circuit complexity of boolean functions, based on a new formalization of "patterns" as elements of a special basis of the vector space of all truth table properties. We prove that a "pattern basis" with certain properties would lead to a useful complexity formula of a specific form, and speculate on how to find such a basis. This formula might take as long to compute on arbitrary functions as a brute-force search among circuits, thus addressing the natural proofs barrier, but has a form amenable to proving lower bounds for well-understood explicit functions.
