弹出算法的紧边界

Tight bounds for popping algorithms

Heng Guo, Kun He

摘要:

我们锐化部分拒绝抽样框架下的算法的运行时分析。我们的方法产生改进的界限:集群弹出算法近似所有终端网络的可靠性;周期弹出算法采样根生成树;下沉弹出算法采样无下沉方向。在这三个应用中,我们的边界不仅是紧的顺序,而且常数最优。

英文摘要:

We sharpen run-time analysis for algorithms under the partial rejection sampling framework. Our method yields improved bounds for: the cluster-popping algorithm for approximating all-terminal network reliability; the cycle-popping algorithm for sampling rooted spanning trees; the sink-popping algorithm for sampling sink-free orientations. In all three applications, our bounds are not only tight in order, but also optimal in constants.
