In the $d$-dimensional hypercube bin packing problem, a given list of
$d$-dimensional hypercubes must be packed into the smallest number of hypercube
bins. Epstein and van Stee [SIAM J. Comput. 35 (2005)] showed that the
asymptotic performance ratio $\rho$ of the online bounded space variant is
$\Omega(\log d)$ and $O(d/\log d)$, and conjectured that it is $\Theta(\log
d)$. We show that $\rho$ is in fact $\Theta(d/\log d)$, using probabilistic
arguments.

在线有界空间超立方体装箱问题的紧下界
在 $d$ 维超立方体装箱问题中,必须将给定的 $d$ 维超立方体列表装入最小数量的超立方体箱中。爱泼斯坦和范斯蒂 [SIAM J. Comput. 35 (2005)]表明在线有界空间变体的渐近性能比$\rho$为$\Omega(\log d)$和$O(d/\log d)$,并推测为$\ Theta(\log d)$。我们使用概率论证明 $\rho$ 实际上是 $\Theta(d/\log d)$。
