Method Detail

getC

public double[] getC()

Specified by:

getC in interface StochasticConstraint

getCSparse

public SparseVector getCSparse()

Specified by:

getCSparse in interface StochasticConstraint

getExtensiveForm

public abstract LinearConstraint[] getExtensiveForm()

Specified by:

getExtensiveForm in interface StochasticConstraint

getH

public double[] getH()

Specified by:

getH in interface StochasticConstraint

getT

public double[][] getT()

Specified by:

getT in interface StochasticConstraint

getTSparse

public SparseVector[] getTSparse()

Specified by:

getTSparse in interface StochasticConstraint

getName

public java.lang.String getName()

Description copied from interface: Constraint

Returns the name of a specific constraint.

When creating a new constraint for a problem, a name can be given to this constraint to identify it later and see, which specific constrains hold and maybe which contradict each other.

Please note: unlike Problem, where the name describes the type of problem instead of the actual instance, here the name the describes the actual instance and not the generic type.

Specified by:

getName in interface Constraint

Returns:

the name of the given constraint

isSatisfiedBy

public abstract boolean isSatisfiedBy(double[] x)

Description copied from interface: Constraint

Evaluates the constraint at input value x and checks if the constraint holds. Returns true if input x satisfies the constraint, false otherwise. The input dimension (i.e. the array.length), must be the same as the target function.

Specified by:

isSatisfiedBy in interface Constraint

Parameters:

x - the position, where the constraint is to be evaluated

Returns:

true if input value x satisfies this constraint, false otherwise

getRHS

public double getRHS()

Description copied from interface: Constraint

Returns the right hand side.

Specified by:

getRHS in interface Constraint

Returns:

right hand side
