Field Details

lineSearch

public ConfigQuasiNewton.LineSearch lineSearch

Specifies which line search algorithm to use

ftol

public double ftol

ftol convergence test. 0 <= ftol <= 1

gtol

public double gtol

gtol convergence test. 0 <= gtol

line_ftol

public double line_ftol

Tolerance for sufficient decrease. ftol > 0. Smaller value for loose tolerance. Try 1e-4

line_gtol

public double line_gtol

Tolerance for curvature condition. gtol ≥ 0. Larger value for loose tolerance. Try 0.9
