I have a goal function that returns the fitness of a given solution. I
need to wrap that function with a class or a function to keep track of
the best solution I encounter. Which of the following would best serve
my purpose and be the most pythonic?
class Goal:
def __init__(self, goal):
self.goal = goal
self.best = None
self.best_score = None
def __call__(self, solution):
score = self.goal(solution)
if self.best is None or score > self.best_score:
self.best_score = score
self.best = solution
return score
def save_best_goal(goal):
def new_goal(solution):
score = goal(solution)
if new_goal.best is None or score > new_goal.best_score:
new_goal.best = solution
new_goal.best_score = score
return score
new_goal.best = new_goal.best_score = None
return new_goal
