在半随机图中精确恢复种植的团

Exact recovery of planted cliques in semi-random graphs

Yash Khanna

AI总结:

本文提出了一种基于SDP的算法,用于在半随机图中精确恢复种植的团,并展示了该算法的保证性能。

摘要:

在本文中,我们研究了半随机模型中的Planted Clique问题。我们的模型受Feige-Kilian模型的启发,该模型已被其他许多工作用于各种图问题。我们的算法和分析在很大程度上与Khanna和Louis在Densest k-subgraph问题中的研究类似。作为主要结果的副产品,我们给出了一个基于SDP的替代舍入算法(具有相似的保证),用于在随机图中解决Planted Clique问题。

英文摘要:

In this paper, we study the Planted Clique problem in a semi-random model. Our model is inspired from the Feige-Kilian model [16] which has been studied in many other works [8,11,17,26,35,38] for a variety of graph problems. Our algorithm and analysis is on similar lines to the one studied for the Densest $k$-subgraph problem in the work of Khanna and Louis [25]. As a by-product of our main result, we give an alternate SDP-based rounding algorithm (with similar guarantees) for solving the Planted Clique problem in a random graph.
