论文摘要
我们研究了图表上宽类过程的稳定时间,在该过程中,每个节点只能通过至少$ \ frac {1+λ} {2} $的邻居分数进行$ 0 <λ<1 $而进行切换。此类过程的两个示例是图形中充分研究的动态变化:在大多数过程中,节点切换到附近最频繁的颜色,而在少数族裔过程中,节点切换到附近最不常见的颜色。我们描述了一个非元素函数$ f(λ)$,我们表明,在顺序模型中,这些过程的最坏情况稳定时间可以完全以$ f(λ)$为特征。更确切地说,我们证明,对于任何$ε> 0 $,$ o(n^{1+f(λ)+ε})$是任何比例多数/少数族裔过程的稳定时间上的上限,并且我们还表明,稳定性确实需要$ω(n^{1+f(λ) - λ) - ε{1+f(λ) - ε})$ speess。
We study the stabilization time of a wide class of processes on graphs, in which each node can only switch its state if it is motivated to do so by at least a $\frac{1+λ}{2}$ fraction of its neighbors, for some $0 < λ< 1$. Two examples of such processes are well-studied dynamically changing colorings in graphs: in majority processes, nodes switch to the most frequent color in their neighborhood, while in minority processes, nodes switch to the least frequent color in their neighborhood. We describe a non-elementary function $f(λ)$, and we show that in the sequential model, the worst-case stabilization time of these processes can completely be characterized by $f(λ)$. More precisely, we prove that for any $ε>0$, $O(n^{1+f(λ)+ε})$ is an upper bound on the stabilization time of any proportional majority/minority process, and we also show that there are graph constructions where stabilization indeed takes $Ω(n^{1+f(λ)-ε})$ steps.
