A PTAS for $ℓ_{0}$ -Low Rank Approximation: Solving Dense CSPs over Reals

Vincent Cohen-Addad, Chenglin Fan, Suprovat Ghoshal +4

We consider the Low Rank Approximation problem, where the input consists of a matrix $A \in R^{n_{R} \times n_{C}}$ and an integer $k$ , and the goal is to find a matrix $B$ of…

Handling Correlated Rounding Error via Preclustering: A 1.73-approximation for Correlation Clustering

Vincent Cohen-Addad, Euiwoong Lee, Shi Li +1

We consider the classic Correlation Clustering problem: Given a complete graph where edges are labelled either $+$ or $-$ , the goal is to find a partition of the vertices that mini…

Hardness of Approximating Bounded-Degree Max 2-CSP and Independent Set on k-Claw-Free Graphs

Euiwoong Lee, Pasin Manurangsi

We consider the question of approximating Max 2-CSP where each variable appears in at most $d$ constraints (but with possibly arbitrarily large alphabet). There is a simple $(\frac…
