Approximability of all Boolean CSPs with linear sketches

no code implementations24 Feb 2021 Chi-Ning Chou, Alexander Golovnev, Madhu Sudan, Santhoshini Velusamy

In this work we consider the approximability of $\textsf{Max-CSP}(f)$ in the context of sketching algorithms and completely characterize the approximability of all Boolean CSPs.

On the computational complexity of the probabilistic label tree algorithms

no code implementations1 Jun 2019 Robert Busa-Fekete, Krzysztof Dembczynski, Alexander Golovnev, Kalina Jasinska, Mikhail Kuznetsov, Maxim Sviridenko, Chao Xu

First, we show that finding a tree with optimal training cost is NP-complete, nevertheless there are some tractable special cases with either perfect approximation or exact solution that can be obtained in linear time in terms of the number of labels $m$.
