DDR13 - Generalized Halton Point Set - 25 dimensions
Generalized Halton point set in 25 dimensions optimized over the star discrepancy by an evolutionary algorithm as described in Doerr and De Rainville 2013.
Point set obtained when searching for the minimal number of points required in 25 dimensions to have a star discrepancy < 0.125. The star discrepancy value is approximated by running 50 times the TA algorithm described in Gnewuch et al. 2012 and available here, with 10 000 iterations each.
Number of Points
The permutation vectors in the JSON file are values of a dictionary where the key is the number of points (as string). Points sets should be read row major; an entire row is a point and each column is one dimension for a point.
