Abstract
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.
