  (default 0.001)
 -V
  Use variant 1 of the algorithm when true, otherwise use variant 2.
  (default true)
 -P <double>
  The epsilon for round-off error.
  (default 1.0e-12)
 -L <double>
  The epsilon parameter in epsilon-insensitive loss function.
  (default 1.0e-3)
 -W <double>
  The random number seed.
  (default 1)
