Topology Optimization is a technique that allows for the obtaining structures which maximize the use of the material. If the rule of all the cells are the same then it is called uniform cellular automata, otherwise, it is called hybrid cellular automata. Section 3 shows that Cellular Automata can not generate random but pseudo-random patterns. This technique makes use of the hybrid cellular automaton framework, which combines transient, non-linear finite-element analysis and local control rules acting on cells.
