| Abstract | In this paper we consider an acceptance-rejection (AR) sampler based on deterministic driver sequences. We prove that the discrepancy of an N element sample set generated in this way is bounded by $$\mathcal {O} (N^{-2/3}\log N)$$ , provided that the target density is twice continuously differentiable with non-vanishing curvature and the AR sampler uses the driver sequence $$\mathcal {K}_M= \{( j \alpha , j \beta ) ~~ mod~~1 \mid j = 1,\ldots ,M\},$$ where $$\alpha ,\beta $$ are real algebraic numbers such that $$1,\alpha ,\beta $$ is a basis of a number field over $$\mathbb {Q}$$ of degree 3. For the driver sequence $$\mathcal {F}_k= \{ ({j}/{F_k}, \{{jF_{k-1}}/{F_k}\} ) \mid j=1,\ldots , F_k\},$$ where $$F_k$$ is the k-th Fibonacci number and $$\{x\}=x-\lfloor x \rfloor $$ is the fractional part of a non-negative real number x, we can remove the $$\log $$ factor to improve the convergence rate to $$\mathcal {O}(N^{-2/3})$$ , where again N is the number of samples we accepted. We also introduce a criterion for measuring the goodness of driver sequences. The proposed approach is numerically tested by calculating the star-discrepancy of samples generated for some target densities using $$\mathcal {K}_M$$ and $$\mathcal {F}_k$$ as driver sequences. These results confirm that achieving a convergence rate beyond $$N^{-1/2}$$ is possible in practice using $$\mathcal {K}_M$$ and $$\mathcal {F}_k$$ as driver sequences in the acceptance-rejection sampler. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
