I'm trying to do parameter estimation (using GA) in my stiffness 1D ODE system.
When GA automatically try various parameter values to fit data, some parameter cases are so sensitive that main function were shut down due to stiffness problem.
In this case, how to handling exception case using "try and catch" ?
In my system, I solve 95 ODEs simultaneously. Among them a parameter affects several ODEs and it cause stiffness problem.
I want to change setting parameter value as zero in case of stiffness problem.
