Mod-p Decision Diagrams: A Data Structure for Multiple-Valued Functions
Multiple-valued decision diagrams (MDDs) give a way of approaching problems by using symbolic variables which are often more naturally associated with the problem statement than the variables obtained by a binary encoding. We present a more general class of MDDs, containing not only branching nodes but also functional nodes, labeled by addition modulo Ô operation, Ô - prime, and give algorithms for their manipulation. Such decision diagrams have a potential of being more space-efficient than MDDs. However, they are not a canonical representation of multiple-valued functions and thus the equivalence test of two Mod-Ô-DDs is more difficult then the test of two MDDs. To overcome this problem, we design a fast probabilistic equivalence test for Mod-Ô-DDs that requires time linear in the number of nodes.
