论文摘要
在流媒体模型中,计算小型子图,特别是周期的问题在过去几年中引起了很多关注。在本文中,我们考虑了任意订单插入的流,对计算4个周期的最新结果改善。我们的算法通过在流上进行三个通行并使用Space $ O(\ frac {m \ log n} {ε^2 t^{1/3}})$来计算$(1+ε)$ - 近似值,其中$ m $是图中的边缘数,$ t $是$ t $的数量。
The problem of counting small subgraphs, and specifically cycles, in the streaming model received a lot of attention over the past few years. In this paper, we consider arbitrary order insertion-only streams, improving over the state-of-the-art result on counting 4-cycles. Our algorithm computes a $(1+ε)$-approximation by taking three passes over the stream and using space $O(\frac{m \log n}{ε^2 T^{1/3}})$, where $m$ is the number of edges in the graph and $T$ is the number of 4-cycles.
