ABSTRACT:
A pointerless BDD package. A strict ordering is enforced on the BDD node identifiers and the advantageous consequences of that decision, such as a better memory locality of the nodes and faster unique table lookup, are reaped. The performance of a pointer based package appears to be exceeded, and reproducible results are attained across different platforms.
