We have studied the Variable Elimination recently and the teacher emphasizes that it is the Bayesian Network that makes varibale elimination more efficient.
I am bit confused on this,why is this the case?
Hope you guys can give me some idea,many thanks.

I think it’s because a variable which one can eliminate is one which has one and only one variable which is dependent on it. In a Bayes net these would be easy to find because they are nodes with a single child.
