Unrecognized field name "ProblemdefOptions".

Hi, I'm trying to run ga with:

options = optimoptions('ga','Display','iter','MaxGenerations',3,'PopulationSize',10,'OutputFcn',@SaveOut);

But get an error:

"Unrecognized field name "ProblemdefOptions".

Error in gaoutput (line 30)

ProblemdefOptions = options.ProblemdefOptions;"

Does anyone have a solution?

Thank you

It sounds as if you are using the problem-based approach. To do so, you might need to specify some options when you call solve, such as Solver="ga" and maybe other options.

For more help, please show your code where you call solve (or ga ) and all of your associated setup code.
