So you are looking for hints on how to convert a ZDD to Reed-Muller-Normal-Form. There you go:

  1. Use Davio-Decomposition to build a FDD and read the RMNF from that.
  2. Non-overlapping-DNF-to-RMNF:
The Non-overlapping-DNF-to-RMNF conversion works like this:
  1. Read the DNF from the ZDD/ROBDD
  2. Make sure that the DNF is non-overlapping (e.g. containing no pair of co-clauses that can be satisfied by the same assignment)
  3. Since the co-clauses don't overlap, you the disjunctions are here the same as excluseive-or. Hence, replace all the OR by XOR.
  4. Now the formula consists of XOR, conjunction, and negation. RMNF doesn't allow negation. Replace ¬X by (1 XOR x)
  5. Multiply the inner XOR-terms out.
