Usage


R1 sampler
Usage: ./Rank1 [OPTIONS]

Options:
  -h,--help                   Print this help message and exit
  -n UINT REQUIRED            Number of points
  -d UINT                     UNUSED ! Here for compatibility with others.
  -s,--seed UINT              UNUSED ! Here for compatibility with others.
  -m UINT [1]                 Number of pointsets
  -o,--out TEXT [out.dat]     Output file (format). {i} splits outputs in multiple files and token is replaced by index.
  -e,--exhaustive [0]         Enable exhaustive search
  -f,--fibonacci [0]          Enable fibonnaci lattice
  --silent                    Silence UTK logs
