Network models
Most of the methods for the modelling and simulation of gene regulatory networks described above have taken a ``bottom up'' approach. They take the interactions between the indvidual elements of a system as their starting point and then observe the global behaviour that results when the system is solved or simulated. Recently, there has been an increasing amount of interest in a ``top down'' approach, focusing first and foremost on the genetic system as a network [90,24]. The most basic feature of any network is its structure, the way in which individual elements are connected together. The structure of a network is constrained by the growth process that produced it and, in turn, constrains the possible dynamics of the system.
