Maximizes the total score of visited places while staying below the maximum distance.
Parameters:
places (list of tuples): Each tuple contains (score, (x, y), location).
max_distance (float): The maximum distance that can be traveled.
fixed_entry (tuple): The place that needs to be visited independently of its score.
top_k (int): Number of top candidates to consider in each iteration.
Returns:
list of tuples: The visited places.
float: The total score of the visited places.
