Modeling our survival in a zombie apocalypse

In this work we applied several concepts on the modeling of complex systems in an attempt to save mankind in the case of a zombie apocalypse. We developed a dynamical system in order to model a zombie outbreak in which we, regular humans, are aided by military personnel in the fight against the zombies. Our analysis has shown that the initial amount of military personnel play a key rule on our survival, even when the zombies are extremely aggressive and in large advantage.This document is a pre-print version of the paper de Mendon\c{c}a, J.P.A., Teixeira, L.M.V., Sato, F. et al.
