I am always keen to learn some crowd psychology.
The question that I had is - why do folks get compelled to download a code that does something wrongly? We already know that it does its own job wrongly. What does it matter how it does it? One wants to marvel the coding style or the number of lines or something?
Very curious.

Actually, algo consists of three stages..

it picks initial (probable) Z’s (pZ_L and pZ_R) up (Z = P + Q, N = P*Q)
Full stop, don't need to read further.
The algorithm now computed P*Q and if it equals N: stop, all done.
Else: stop because there is no point in going further :-)

Arguing that it is better because "it doesn't use division and (untrue) doesn't use modular arithmetic" is false because it competes with the Algorithm 2: "Compute P*Q. If equal N, stop. Done" and loses.
