Hi All,

I get a error message while using sim command ( simulate dynamic system) inside Fitness function which i use for Genetic algorithm.

I know the error is Singularity problem. All i want to know is.. Is there any way by which i can overcome this error. ( that is i want ga to leave those input values and go further with its next search something like try catch go error handling block?)

Thank you in Advance.

If i understood what you mean, your problem is that for some values you get an error. In this case you can set your constraints in a way that those values are not produced by the ga.

Thank you so much for replying dimitris

However I dont have mathematical equation to tell at which place those errors might occur. So i want ga to ignore the current input value and try next in the search.

And yes i think you have understood my problem.
