Dear Steven (or anyone else), is it possible to save optimization progress, so in case of a machine freezing the process does not need to be restarted from the beginning?
Namely, I have been running some global optimization for a week only to find out this morning that the machine has frozen (become unresponsive) sometime overnight. I had to restart it, and of course all the programs are not running any more. I have a log file with records of all evaluations of the objective function (parameter values and function value), but I don't think I can resume global optimization from this. I use GN_DIRECT_L, and it is nowhere near convergence (the best value in log file is 0.31 and maximum obtained using LN_COBYLA is 0.68). Can I use some trick to save/load optimizer state, such as writing/reading contents of nlopt::opt variable? Regards, Dženan
