enum GSL::MultiMin::AlgorithmFDF

Defined in:

gsl/maths/optimization/multimin.cr

Enum Members

ConjugateFR = 0: This is the Fletcher-Reeves conjugate gradient algorithm.
ConjugatePR = 1: This is the Polak-Ribiere conjugate gradient algorithm.
BFGS = 2: This method use the vector Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm.
BFGS2 = 3: This method is the most efficient version available
SteepestDescent = 4: The steepest descent method is inefficient and is included only for demonstration purposes.

Description copied from struct Enum

Returns a String representation of this enum member. In the case of regular enums, this is just the name of the member. In the case of flag enums, it's the names joined by vertical bars, or "None", if the value is zero.

If an enum's value doesn't match a member's value, the raw value is returned as a string.

Color::Red.to_s                     # => "Red"
IOMode::None.to_s                   # => "None"
(IOMode::Read | IOMode::Write).to_s # => "Read | Write"

Color.new(10).to_s # => "10"
