EPS_STEP_SIZE: real = 1.00000000E-001

Convergence criterion of GOLD method. [Edit on GitHub]

INITIAL_STEP_SIZE: real = 1.00000000E-001

Initial step length [Edit on GitHub]

MAX_STEP_SIZE: real = 3.00000000E+000

Maximum step length [Edit on GitHub]

METHOD: enum = ADAPT

Valid values:

• ADAPT extrapolates usually based on 3 points, uses additional points on demand, very robust.

• 3PNT extrapolate based on 3 points

• 2PNT extrapolate based on 2 points and the slope (super fast, but might get stuck at saddle points)

• GOLD perform 1D golden section search of the minimum (very expensive)

• NONE always take steps of fixed INITIAL_STEP_SIZE
