Derived Types

type, public :: iteration_behavior

Defines a set of parameters that describe the behavior of the iteration process.

Components

Type	Visibility	Attributes		Name		Initial
logical,	public		::	converge_on_chng			True if the solution converged as a result of no appreciable change in solution points between iterations; else, false.
logical,	public		::	converge_on_fcn			True if the solution converged as a result of a zero-valued function; else, false.
logical,	public		::	converge_on_zero_diff			True if the solution appears to have settled on a stationary point such that the gradient of the function is zero-valued; else, false.
integer(kind=int32),	public		::	fcn_count			Specifies the number of function evaluations performed.
integer(kind=int32),	public		::	gradient_count			Specifies the number of gradient vector evaluations performed.
integer(kind=int32),	public		::	iter_count			Specifies the number of iterations performed.
integer(kind=int32),	public		::	jacobian_count			Specifies the number of Jacobian evaluations performed.
