Softwares

• MOC : simulation software for the following four chemostat models:
  * IBM : a hybrid stochastic model composed of an individual-based and mass-structured model coupled with a differential equation;
  * EID : a mass-structured integro-differential model coupled to a differential equation;
  * Crump-Young : a hybrid stochastic model composed of a birth and death process coupled with a differential equation;
  * EDO : the classical model of the chemostat consisting of a system of two differential equations.
