Constructor Detail

SqrtPeqR

public SqrtPeqR(FloatVar p,
                FloatVar r)

It constructs a constraint sqrt(P) = R.

Parameters:

p - variable p.

r - variable r.

Method Detail

consistency

public void consistency(Store store)

Description copied from class: Constraint

It is a (most probably incomplete) consistency function which removes the values from variables domains. Only values which do not have any support in a solution space are removed.

Overrides:

consistency in class PmulQeqR

Parameters:

store - constraint store within which the constraint consistency is being checked.

toString

public String toString()

Description copied from class: Constraint

It produces a string representation of a constraint state.

Overrides:

toString in class PmulQeqR

derivative

public FloatVar derivative(Store store,
                           FloatVar f,
                           Set<FloatVar> vars,
                           FloatVar x)

Overrides:

derivative in class PmulQeqR
