It should be noted that the term "analyzer" appears exactly ONCE in this 
document outside of the bibliography (compared to 46 for "termination 
analysis"), and that it focuses on the process of finding answers in 
some cases.

The point is that your HHH doesn't give the answer that a halt decider / 
termination analyzer is stipulated to provide for DD.
