What is Automata

The topic of this chapter covers viral bio-modeling. This chapter applies finite states automata to translate the stages of some viral invasions, from a natural language, into a flowchart encountered in the automata theory. In previous work, viruses with multiplication targets inside the nucleus of the host cell, typical DNA viruses, were investigated. Now, generalized flowcharts are proposed even for RNA viruses. The main scope of this work is to establish clear states, input variables, and output command functions for viral invasions inside a host cell. The chapter also proposes some applications. One of them concerns the new anti-viral drugs development, based on the virus failure at different tests encountered in the flowchart. The second application concerns the development of bio-inspired circuits.
