The general BP inference (belprop_inf_engine) engine for bayesian networks does 
not compute marginals properly on even the simplest networks. The Pearl BP 
inference engine works flawlessly, but the general BP engine for bayesian 
networks does not. The general BP inference engine for factor graphs works 
properly also. 


Thanks,

Jason

The belprop_inf_engine gives incorrect results of the MPE as well.
The MPE returned by the belprop_inf_engine is different from the ones 
calculated by other engines for the Cloudy/Rain/Sprinkler/Wet network.

I attach a script to reproduce the error.
