The max_wall_time and max_cpu_time are not working in ipopt (cyipopt).
See example:
nlp = cyipopt.Problem(n=len(x0), m=len(cl), problem_obj=HS071(),
lb=lb, ub=ub, cl=cl, cu=cu)
The following are not working:
nlp.add_option('max_wall_time', 20)
nlp.add_option('max_cpu_time', 20)
it says TypeError: Error while assigning an option.
Any idea about how to set these stopping criteria in ipopt (cyipopt)?
The solution is shown below. I just figured that out, so I thought it would be better to leave the question that might be helpful for others.
It accepts float rather than integer!
nlp.add_option('max_wall_time', 20.0)
nlp.add_option('max_cpu_time', 20.0)
