So, while working at the HW4, I had to change a part of my code, and as a byproduct of that I had an empty function that was never called and didn't do anything at all. For some time I forgot about it, fast forward some hours and I go to try the intricacy of my code and I see that the aforementioned function reduced the intricacy, just by being there. As a test I tried adding 15 empty function that only returned 0 and that got my intricacy very, very low. I just wanted to report this, I wish good luck to all for HW4!
