  Starting from the idea that the underlying mechanisms driving the observable
processes in nature are algorithmic, we exemplify this in two ways: nature
works as a computing machine and thus the processes running on it optimize
themselves in an intrinsic manner so as to save time. As a first example we
will place the empirical analysis of oxidation in the context of algorithm
complexity analysis. Second, we will show that deformations suffered by a
shape-memory alloy may be produced by nature showing a LIFO (Last In First Out)
behaviour.
