Matlab GA toolbox coupling with external simulation code.

I have the following problem when using GA tool for optimization. My objective function is the result of simulating each population in an external code. My question is: how can I handle the evaluation of the objective function for each population, running the simulation code for each individual.

Are you able to call the external simulation code from MATLAB, pass it some parameters, and get the output in return?

See if the approach in Parameter Estimation for a System of Differential Equations will do what you want. It uses the ga function to optimise the parameters for differential equations integrated using ode45.

The diagram simply outlines the essence of the genetic algorithm.
You can likely substitute ‘ERANOS’ for ‘kinetics’ in my code, obviously with the appropriate changes. (I have no idea what ‘ERANOS’ is, so I cannot help you with it.)

You can write a MATLAB function wrapper around the call to the external simulator. Something like this
function f = objFun(x)
% call your external simulation here, pass value of x
% and return the objective function value y.
y = call_external_simulation(x);
end
