FALSE:

HHH[0] emulates zero instructions of DD[0]
HHH[1] emulates one  instructions of DD[1]
HHH[n] emulates n    instructions of DD[n]
HHH[∞] emulates ∞    instructions of DD[∞]

False, because the algorithm DD consists of the machine code of the 
function DD, the function HHH, and the machine code of everything that 
HHH calls down to the OS level.

So when you hypothesize changing the code of the function HHH, you're 
hypothesizing changing the input algorithm DD.

Changing the input is not allowed.
