    "abstract": "To better understand the deep significance of our best physical theories it\ncould be interesting to compare our Universe with its models. It may happen\nthat the differences between the model and reality can be made\nindistinguishable, to the point that it may seem acceptable to consider reality\nas a gigantic program, a \u0027mother computation\u0027 running in a Universal Computer.\nThe computational interpretation of reality is here adopted for introducing\nconcepts that are common in computer science, they may offer a new insight. For\ninstance, code and memory usage optimization techniques are common in computer\nscience because they improve the performances at a reduced hardware cost.\nAccording to the concepts discussed in this paper, the possibility of\nrecognizing the effects of optimization rules in a physical reality will allow\nus to discriminate if our reality is fundamental or the result of a large\ncomputation. Conversely, code and memory optimization has side effects, if it\nis present in our Universe it can produce many interesting phenomena, some seem\nreadily recognizable, others only wait to be discovered.",
