cocoex.python.utilities.ProblemNonAnytime : API documentation

The non-anytime problem class.

Serves to benchmark a "budgeted" algorithm whose behavior decisively depends on a budget input parameter.

Usage:

# given: suite and observer instances, budget_list, fmin
for index in range(len(suite)):
    with ProblemNonAnytime(suite, observer, index) as problem:
        x0 = problem.initial_solution  # or whatever fmin needs as input
        for budget in sorted(budget_list):
            x = fmin(problem, x0, budget)  # minimize
            problem.delivered(x)  # prepares for next budget also
            if problem.final_target_hit:
                break

Details: This class maintains two problems - one observed and the other unobserved. It switches from unobserved to observed when p_unobserved.evaluations >= p_observed.evaluations.

def __call__(self, x, *args, **kwargs):

Undocumented

def delivered(self, x, *args, **kwargs):

to be called with the solution returned by the solver.

The method records the delivered solution (if necessary) and prepares the problem to be run on the next budget by calling reset.

def reset(self):

prepare the problem to be run on the next budget
