Modifier and Type	Method	Description
GradientGuidedPath	CompositePathOptimiser.initState(GeneralTask t)	Creates a new Path instance for storing the gradient, direction, and minimum point for this PathSolver.
GradientGuidedPath	LMOptimiser.initState(GeneralTask t)
GradientGuidedPath	SteepestDescentOptimiser.initState(GeneralTask t)	Creates a new Path instance for storing the gradient, direction, and minimum point for this PathSolver.

Methods in pulse.search.direction with parameters of type GradientGuidedPath

Modifier and Type	Method	Description
Vector	DirectionSolver.direction(GradientGuidedPath p)	Finds the direction of the minimum using the previously calculated values stored in p.
default Vector	HessianDirectionSolver.direction(GradientGuidedPath p)	Uses an approximation of the Hessian matrix, containing the information on second derivatives, calculated with the BFGS formula in combination with the local value of the gradient to evaluate the direction of the minimum on p.
