"The main problem that systems theory tries to solve is the problem of complexity. The notion of complexity is very often correlated to variables such as entropy and energy, organization and disorganization and others that eventually converge to comprehensibility or incomprehensibility" (Mavrofides, Kameas, Papageorgiou, & Los, 2011, p
"A fundamental notion of general systems theory is its focus on interactions. The center in relationships lead to sustain that the behavior of a single autonomous element is different from its behavior when the element interacts with other elements" (Mele, Pels, & Polese, 2010, p
