Resumo: We present symbolic methods to deal with complex systems which vary in time. The complex systems are characterized by graphs or networks, expressing internal relations, with a huge number of parts and different types of structures. Cellular automata are used to codify evolutionary and development processes for the structure of the referred systems.
