Enumeration with One Dimensional Minimizer Algorithms.

The algorithms are implemented using GSL, see the GSL manual.

The algorithms available are:

  • Golden Section Algorithm, simplest method of bracketing the minimum of a function
  • Brent Algorithm, which combines a parabolic interpolation with the golden section algorithm
