Improved variants of the Hutch++ algorithm for trace estimation

davpersson/a-hutch- 22 Sep 2021

In this work, we derive an adaptive variant of Hutch++, which outputs an estimate of the trace that is within some prescribed error tolerance with a controllable failure probability, while splitting the matrix-vector products in a near-optimal way among the two phases.
