The Shared Binary Decision Diagram (SBDD) with negative edge attributes can represent many functions in a compact form if a proper variable ordering is used. In this work we describe a technique for reordering the variables in an SBDD to reduce the size of the data structure. We use a heuristic to formulate a technique for the reordering problem based on probability metrics.
