It has been widely observed that most deterministic dynamical systems go into chaos for some values of their parameters. There are many ways to measure chaos. One popular way uses Lyapunov exponents. The objective of this thesis is to find the parameter values for a system that determines chaos via the Lyapunov exponents.The paper by Wolf, proposed the frequently used choice of calculating such exponents using Gram-Schmidt orthonormalization process. The work in this thesis centered on coding and verifying their algorithm , as well as using the code to investigate three biological models to find parameters/initial conditions to give chaos. Finally it also considers as future work choosing appropriate sampling algorithms to better understand the parameter space for which we may obtain chaos.
