The package "paropt" was build for optimizing parameters of ODE-systems. Thus, the aim is that the output of an integration of the ODE system using the optimaized parameters matches the given model states. The user has to supply an ODE-system in the form of a Rcpp-function. The information about states and parameters are passed via text-files. Additional information such as, e.g., the relative tolerance are passed within R.
Application of the two functions, "ode_solving" and "optimizer" is demonstrated for the Lotka-Volterra predator / prey system as an example that demonstrates how the package can be used.
