I finally gave up this attempt and edited my code to save checkpoint file every iteration rather than overwrite it. The implementation is based on 'OutputFcn' in optimoptions. So next time I can restart the optimization process from any iteration.
Can I restart surrogateopt from earlier iterations with checkpoint file?

My surrogateopt stopped because of external program crash, and I'm sure several function evaluations near the crash is not reliable. Thus, I want to restart surrogateopt from earlier iterations rather than resuming from the itertaion that the checkpoint file ends. Is it possible?
