Model parameters need to be expanded to include functional forms in the demand-supply modelling technique. Examples include:
growth rate and mortality rate as a function of temperature
oviposition preference as a function of fruit age
variable growth rates of parasite as a function of fruit age
response functions of temperature, humidity, nitrogen, etc.
degree days as a function of time
Proposed features
We will expand the Parameters class to include:
A library of functional forms
The facility to combine parameters together from basic parameters or functional forms, with the defaults being multiplication and division.
A full integration of functional forms as instances of SymPy functions, with templates providing the functionality we want. This includes the facility of dealing with non-float inputs to these functions - potentially this means storing eg. lists as SymPy objects as well.
