Function Documentation

DdNode* Cudd_bddAndAbstract ( DdManager manager,
DdNode f,
DdNode g,
DdNode cube 
)

Takes the AND of two BDDs and simultaneously abstracts the variables in cube.

The variables are existentially abstracted. Cudd_bddAndAbstract implements the semiring matrix multiplication algorithm for the boolean semiring.

Returns:
a pointer to the result is successful; NULL otherwise.
Side effects
None

DdNode* Cudd_bddAndAbstractLimit ( DdManager manager,
DdNode f,
DdNode g,
DdNode cube,
unsigned int  limit 
)

Takes the AND of two BDDs and simultaneously abstracts variables unless too many nodes are needed.

The variables in cube are existentially abstracted.

Returns:
a pointer to the result is successful; NULL otherwise. In particular, if the number of new nodes created exceeds limit, this function returns NULL.
Side effects
None

DdNode* cuddBddAndAbstractRecur ( DdManager manager,
DdNode f,
DdNode g,
DdNode cube 
)

Takes the AND of two BDDs and simultaneously abstracts the variables in cube.

The variables are existentially abstracted.

Returns:
a pointer to the result is successful; NULL otherwise.
