We consider an acceptance-rejection sampler based on a deterministic driver sequence. The deterministic sequence is chosen such that the discrepancy between the empirical target distribution and the target distribution is small. We use quasi-Monte Carlo (QMC) point sets for this purpose. The empirical evidence shows convergence rates beyond the crude Monte Carlo rate of N-1/2. We prove that the discrepancy of samples generated by the QMC acceptance-rejection sampler is bounded from above by N-1/s. A lower bound shows that for any given driver sequence, there always exists a target density such that the star discrepancy is at most N-2/(s+1). For a general density, whose domain is the real state space ℝs-1, the inverse Rosenblatt transformation can be used to convert samples from the (s-1)-dimensional cube to ℝs-1. We show that this transformation is measure preserving. This way, under certain conditions, we obtain the same convergence rate for a general target density defined in ℝs-1. Moreover, we also consider a deterministic reduced acceptance-rejection algorithm recently introduced by Barekat and Caflisch [F. Barekat and R. Caflisch, Simulation with Fluctuation and Singular Rates. ArXiv:1310.4555 [math.NA], 2013].
