Some Remarks on the Gram-Schmidt Walk Algorithm and Consequences for the Komlós Conjecture
摘要
In this paper, we improve the best known constant for the discrepancy formulated in the Komlós Conjecture. The result is based on an improvement of the sub-Gaussian bound for the random vector constructed in the Gram-Schmidt Random Walk algorithm. Moreover, we present detailed argument for the smoothed analysis of this random vector. The analysis concerns a modification of a given matrix in the conjecture by a Gaussian type perturbation. Our result improves on a recent paper in this direction Bansal et al. (Smoothed Analysis of the Komlós Conjecture (2022). arXiv:2204.11427).
