基于高阶算子的快速黑箱算法
Faster Black-Box Algorithms Through Higher Arity Operators
摘要:
我们扩展了Lehre和Witt(GECCO 2010)关于无偏黑箱模型的工作,考虑了更高的变异算子。特别是,我们表明,已经为二进制运营商的\leadingones的黑盒复杂性下降,从$Θ(n^2)$为一元运营商的$O(n \log n)$。对于\onemax,在二进制情况下,$Ω(n \log n)$一元黑盒复杂度下降到O(n)。对于$k$ -元算子$k \leq n$,\onemax -复杂度进一步降低到$O(n/\log k)$ .
英文摘要:
We extend the work of Lehre and Witt (GECCO 2010) on the unbiased black-box model by considering higher arity variation operators. In particular, we show that already for binary operators the black-box complexity of \leadingones drops from $Θ(n^2)$ for unary operators to $O(n \log n)$. For \onemax, the $Ω(n \log n)$ unary black-box complexity drops to O(n) in the binary case. For $k$-ary operators, $k \leq n$, the \onemax-complexity further decreases to $O(n/\log k)$.
