Center node: "augmenting ordered binary decision diagrams with conjunctive decomposition"
  Abstract: This paper augments OBDD with conjunctive decomposition to propose a generalization called OBDD[^]. By imposing reducedness and the finest^-decomposition bounded by integer i (^b -decomposition) on OBDD[^], we identify a family of canonical languages called ROBDD[^bi ], where ROBDD[^b ] is equivalent to ROBDD. We show that the succinctness of ROBDD[^bi ] is strictly increasing when i increases. We introduce a new time-efficiency criterion called rapidity which reflects that exponential operations may be preferable if the language can be exponentially more succinct, and show that the rapidity of each operation on ROBDD[^bi ] is increasing when i increases; particularly, the rapidity of some operations (e.g., conjoining) is strictly increasing. Finally, our empirical results show that: a) the size of ROBDD[^bi ] is normally not larger than that of its equivalent ROBDD[^[+1 ]; b) conjoining two ROBDD[^b ]s is more efficient than conjoining two ROBDD[^b]s in most cases, where the former is NP-hard but the latter is in P; and c) the space-efficiency of ROBDD[^c 1] is comparable with that of d-DNNF and that of another canonical generalization of ROBDD called SDD.
