2021 arXiv   pre-print
We present a randomized approximation scheme for the permanent of a matrix with nonnegative entries.  ...  Our scheme extends a recursive rejection sampling method of Huber and Law (SODA 2008) by replacing the upper bound for the permanent with a linear combination of the subproblem bounds at a moderately large  ...  Approximating the Permanent with Deep Rejection Sampling Supplement A Algorithms A.1 Gamma Bernoulli acceptance sheme For any ∈ (0, 3/4), the Gamma Bernoulli acceptance scheme, GBAS, due to Huber  ...
