Identifies the complexity of directed cycles in belief networks

Points out the gap in existing literature on this problem

Suggests the importance of developing methods to handle cycles

Abstract

The most difficult task in probabilistic reasoning may be handling directed cycles in belief networks. To the best knowledge of this author, there is no serious discussion of this problem at all in the literature of probabilistic reasoning so far.
