Hard to believe as their behaviour is so different and you don't

Except that the prediction for the second one is wrong. The simulation of an aborting and halting function, like HHH, does not need to be aborted.

 I proved otherwise. When the abort code is commented out
then it keeps repeating again and again, thus conclusively
proving that is must be aborted or HHH never halts.

 

This is proved when it is simulate by HHH1. HHH aborts after two recursions, which is not an infinite execution.

We know you really, really wants it to be correct. So, you are cheating by suppressing part of the trace, in order to hide the conditional branch instructions in the second case. But no matter how much olcott wants it to be correct, or how many times olcott repeats that it is correct, it does not change the fact that such a simulation is incorrect
