Detailed Description

CGSolver Descriptor helps to implement fluid interface patter on python it encapsulates functionality concerning creation of the CG-Solver.

Constructor & Destructor Documentation

__init__()

def python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__init__	(		self,
			builder
	)

Constructor.

Parameters

builder

LearnerBuilder which creates this Descriptor

References python.learner.LearnerBuilder.LearnerBuilder.GridDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.StopPolicyDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.SpecificationDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__builder, and python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__solver.

Member Function Documentation

__getattr__()

def python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__getattr__	(		self,
			attr
	)

Overrides built-in method if method called is not a object method of this Descriptor, most probably it's a method of LearnerBuilder so it tries to call the method from our builder.

Parameters

attr	String for method name

Returns

: Method calling in LearnerBuilder

References python.learner.LearnerBuilder.LearnerBuilder.GridDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.StopPolicyDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.SpecificationDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__builder, python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__solver, and python.learner.LearnerBuilder.LearnerBuilder.getLearner().

withAccuracy()

def python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.withAccuracy	(		self,
			accuracy
	)

Defines the accuracy of CG-Solver.

Parameters

accuracy

float for accuracy

Returns

: CGSolverDescriptor itself

References python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__solver.

withAlphaReusing()

def python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.withAlphaReusing

(

self

)

The reusage of previous alpha data in the CG iteration.

Returns

: CGSolverDescriptor itself

References python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__solver.

withImax()

def python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.withImax	(		self,
			imax
	)

Defines the maxinmal number of iterations in CG algotihms.

Parameters

imax	integer for maximal number of iteration in CG

Returns

: CGSolverDescriptor itself

References python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__solver.

withThreshold()

def python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.withThreshold	(		self,
			threshold
	)

Defines the maximal accuracy.

If the norm of the residuum falls below this threshold, stop the CG iterations

Parameters

threshold

maximal accuracy

Returns

: CGSolverDescriptor itself

References python.learner.LearnerBuilder.LearnerBuilder.CGSolverDescriptor.__solver.
