public enum class SparseCurvatureMethod

type SparseCurvatureMethod

Automatic	0	Uses a supplied Hessian matrix, numerical recovery from a matrix template, or limited-memory BFGS, in that order.
Supplied	1	Requires a Lagrangian Hessian matrix supplied through Hessian.
Numerical	2	Recovers sparse Lagrangian curvature by differencing first derivatives using a supplied pattern.
LimitedMemoryBfgs	3	Builds a compact BFGS approximation without storing a dense Hessian.
