Member Function Documentation

calculateGradient()

void OptimCostBinary::calculateGradient ( const VectorDouble &  indic, const VectorDouble &  lambda, double *  out  )

virtual

Calculate the Gradient

Parameters

[in]	indic	Array containing the Facies indicators (see remarks) (Dimension: npoint)
[in]	lambda	Array of input values
[out]	out	Array of output gradients

Implements IOptimCost.

getNPoint()

int OptimCostBinary::getNPoint

(

)

const

Returns the Number of Data Points

getNVertex()

int OptimCostBinary::getNVertex

(

)

const

Returns the Number of Meshing Vertices

isInitialized()

int OptimCostBinary::isInitialized ( ) const

inline

minimize()

VectorDouble OptimCostBinary::minimize	(	VectorDouble &	indic,
		bool	verbose = false,
		int	maxiter = 100,
		double	eps = 5.e-4
	)

Perform the minimization

Returns

The array of facies proportions (Dimension: nvertex)

Parameters

[in]	indic	Array containing the Facies indicators (see remarks) (Dimension: npoint)
[in]	verbose	Verbose flag
[in]	maxiter	Maximum number of iterations for Optimization algo.
[in]	eps	Tolerance for Optimization algorithm

Remarks

The argument 'indic' should contain 0 or 1 for active constraints

The inactive constraints should be set to TEST.

reset()

void OptimCostBinary::reset	(	PrecisionOp *	pmat,
		const ProjMatrix *	projdata,
		const ProjMatrix *	projseis = nullptr,
		const VectorDouble &	propseis = VectorDouble(),
		const VectorDouble &	varseis = VectorDouble()
	)

Initialize the Binary Cost Operator

Parameters

[in]	pmat	The precision matrix to be optimized
[in]	projdata	The Projection operator between Data and Meshing
[in]	projseis	The Projection operator between Seismic and Meshing
[in]	propseis	Array of facies proportions
[in]	varseis	Array of variance attached to the seismic

setMeanProportion()

int OptimCostBinary::setMeanProportion

(

double

meanprop

)

Set the Mean proportion for the indicator

Parameters

[in]

meanprop

Value of the mean proportion (raw scale)

setPreCondParams()

void OptimCostBinary::setPreCondParams ( int  chebncmax = 10001, double  chebtol = 5.e-3  )

inline

Set the constant parameters for internal Pre-Conditioner

toggleSeismic()

void OptimCostBinary::toggleSeismic

(

bool

status

)

Toggle the use of the Seismic constraint

Parameters

[in]

status

Status assigned to the Seismic Constraints

Remarks

When the Seismic is not defined (i.e. 'projSeis not defined)

this function is useless
