A gene expression system ra-BDD (n-output Binary Decision Diagram) was proposed in order to investigate co-evolution [5]. Although the system is suitable for behavior models of agents, it does not include crossover. This paper proposes a crossover operation using Bryant’s Apply operation [2]. The operation makes an n-BDD probabilistically inherit two functions expressed by two n-BDDs. In an experiment...
This paper proposes an abductive reasoning system, which can find most preferable solution efficiently, using Binary Decision Diagrams. We propose a specialized BDD and its operation suitable for abductive reasoning: PBDD (Partial BDD) and GPC (Graft & Pruning Construction). We have implemented PBDD and GPC algorithm and built a cost-based abductive reasoning system which can find much more efficiently...
