enum GSL::MultiRoot::AlgorithmF

Defined in:

Enum Members

HybridScaled = 0

This is a version of the Hybrid algorithm which replaces calls to the Jacobian function by its finite difference approximation.

Hybrid = 1

This is a finite difference version of the Hybrid algorithm without internal scaling.

DiscreteNewton = 2

The discrete Newton algorithm is the simplest method of solving a multidimensional system. The algorithm may become unstable if the finite differences are not a good approximation to the true derivatives.

Broyden = 3

The Broyden algorithm is a version of the discrete Newton algorithm which attempts to avoids the expensive update of the Jacobian matrix on each iteration. This algorithm is included only for demonstration purposes, and is not recommended for serious use.
