P. Winker et Kt. Fang, APPLICATION OF THRESHOLD-ACCEPTING TO THE EVALUATION OF THE DISCREPANCY OF A SET OF POINTS, SIAM journal on numerical analysis, 34(5), 1997, pp. 2028-2042
Efficient routines for multidimensional numerical integration are prov
ided by quasi-Monte Carlo methods. These methods are based on evaluati
ng the integrand at a set of representative points of the integration
area. A set may be called representative if it shows a low discrepancy
. However, in dimensions higher than two and for a large number of poi
nts the evaluation of discrepancy becomes infeasible. The use of the e
fficient multiple-purpose heuristic threshold-accepting offers the pos
sibility to obtain at least good approximations to the discrepancy of
a given set of points. This paper presents an implementation of the th
reshold-accepting heuristic, an assessment of its performance for some
small examples, and results for larger sets of points with unknown di
screpancy.
