二元价值函数的黑盒复杂性

Black-Box Complexity of the Binary Value Function

Nina Bulanova, Maxim Buzdalov

摘要:

二进制价值函数,或BinVal,已经出现在演化计算理论的几项研究中,作为线性伪布尔函数的一个极端例子。它的无偏黑盒复杂度以前被证明是最多$\lceil \log_2 n \rceil + 2$,其中$n$是问题的大小。我们用$\log_2 n + 2.42141558 - o(1)$的上界来增加它,这对于$n$的许多值来说更精确。我们还提出了一个下界的$\log_2 n + 1.1186406 - o(1)$。此外,我们证明了BinVal是一个最简单的函数中的所有单峰伪布尔函数至少无偏算法。

英文摘要:

The binary value function, or BinVal, has appeared in several studies in theory of evolutionary computation as one of the extreme examples of linear pseudo-Boolean functions. Its unbiased black-box complexity was previously shown to be at most $\lceil \log_2 n \rceil + 2$, where $n$ is the problem size. We augment it with an upper bound of $\log_2 n + 2.42141558 - o(1)$, which is more precise for many values of $n$. We also present a lower bound of $\log_2 n + 1.1186406 - o(1)$. Additionally, we prove that BinVal is an easiest function among all unimodal pseudo-Boolean functions at least for unbiased algorithms.
