Function Documentation

◆ addCheckPositiveCube()

static int addCheckPositiveCube	(	DdManager *	manager,
		DdNode *	cube
	)

static

Checks whether cube is an ADD representing the product of positive literals.

Returns: 1 in case of success; 0 otherwise.

Side effects None

◆ Cudd_addExistAbstract()

DdNode* Cudd_addExistAbstract	(	DdManager *	manager,
		DdNode *	f,
		DdNode *	cube
	)

Existentially Abstracts all the variables in cube from f.

Abstracts all the variables in cube from f by summing over all possible values taken by the variables.

Returns: the abstracted ADD.

Side effects None

◆ Cudd_addOrAbstract()

DdNode* Cudd_addOrAbstract	(	DdManager *	manager,
		DdNode *	f,
		DdNode *	cube
	)

Disjunctively abstracts all the variables in cube from the 0-1 ADD f.

Abstracts all the variables in cube from the 0-1 ADD f by taking the disjunction over all possible values taken by the variables.

Returns: the abstracted ADD if successful; NULL otherwise.

Side effects None

	)

Universally Abstracts all the variables in cube from f.

Abstracts all the variables in cube from f by taking the product over all possible values taken by the variable.

Returns: the abstracted ADD if successful; NULL otherwise.

Returns the ADD obtained by abstracting the variables of cube from f, if successful; NULL otherwise.

Side effects None

◆ cuddAddOrAbstractRecur()

DdNode* cuddAddOrAbstractRecur	(	DdManager *	manager,
		DdNode *	f,
		DdNode *	cube
	)

Performs the recursive step of Cudd_addOrAbstract.

Returns: the ADD obtained by abstracting the variables of cube from f, if successful; NULL otherwise.

Side effects None

◆ cuddAddUnivAbstractRecur()

DdNode* cuddAddUnivAbstractRecur	(	DdManager *	manager,
		DdNode *	f,
		DdNode *	cube
	)

Performs the recursive step of Cudd_addUnivAbstract.

Returns: the ADD obtained by abstracting the variables of cube from f, if successful; NULL otherwise.

Side effects None
