Quasirandom SequenceA sequence of -tuples that fills -space more uniformly than uncorrelated random points. Such a sequence is extremelyuseful in computational problems where numbers are computed on a grid, but it is not known in advance how fine the grid must beto obtain accurate results. Using a quasirandom sequence allows stopping at any point where convergence is observed, whereas theusual approach of halving the interval between subsequent computations requires a huge number of computations between stoppingpoints.
