Cellular automata (CA) is a modeling technique that has the potential of investigating the behavior of complex systems. Recently, it has been considered a tool for understanding social phenomena. CA studies complex systems by studying the behavior of their entities at the micro-level and their interactions to produce this bottom-up formation of complex social system. This thesis applies CA to the problem of illiteracy in Egypt in an attempt to understand the phenomenon and to detect the vital barriers that obstruct the illiteracy eradication from the Egyptian society. In contrast to the former analytical studies that have been focusing on the macro-level properties of the problem by studying its aggregated parameters, this thesis will focus on studying this phenomenon on the micro-level by tracking its bottom-up pattern that emerges through the interaction between each person in the society and his/her neighborhood.
