Discrepancy Minimization via a Self-Balancing Walk
SIAM Journal on Computing, Ahead of Print. Abstract. We study discrepancy minimization for vectors in [math] under various settings. The main result is the analysis of a new simple random process in high dimensions through a comparison argument. As corollaries, we obtain bounds which are tight up to logarithmic factors for online vector balancing against oblivious adversaries, resolving several questions posed by Bansal et al. [STOC, ACM, New York, 2020, pp. 1139–1152], as well as a linear time algorithm for logarithmic bounds for the Komlós conjecture.
期刊介绍:
