    hello everybody;
    i am using UnBBayes and OOBN in instance i handle both the two successfully.
    now my question i want to know wich algorithme was implimented in MSBN and OOBN in order to compile an MSBN instance?
    Kind regards.

      I think the algorithm which is used in UnBBayes-OOBN for converting OOBN to MSBN is not published in the web. But the idea is extremely simple: convert each instance of a class to a section (sub-network) in MSBN.

      Once the MSBN is generated, the algorithm which compiles (i.e. computes the probabilities) the MSBN is a Junction Tree/Forest algorithm of Yang Xiang. Please, refer to the following publications (or other publications of same author) as starting points:

      XIANG, Yang. Verification of DAG Structures in Cooperative Belief Networks Based Multi-Agent Systems. Networks, [S.l.], n.31, p.183-191, 1998.

      XIANG, Yang. Cooperative Triangulation in MSBNs without Revealing Subnet structures. Regina: Department of Computer Science, 1998. 22p. Technical Report CS-98-02.

      Best.
