上述代码的new_points代表什么

在上述代码中，`new_points` 是用于进行插值的新点坐标。它是一个二维数组，每行表示一个新点的坐标。这些新点将通过TPS插值算法来计算对应的插值结果。

在TPS插值中，我们需要确定一组控制点及其对应的值，然后根据这些控制点之间的映射关系来计算插值结果。通过指定新点的坐标，我们可以根据控制点之间的映射关系来计算出这些新点的插值结果。

在示例代码中，`new_points` 是一个随机生成的二维坐标数组，表示了我们希望进行插值的新点的位置。这些新点的插值结果将通过TPS插值算法计算得出，并保存在 `interpolated_values` 中。

您可以根据您实际的应用需求，提供适当的新点坐标来进行插值，并获取相应的插值结果。

可以将 `visited_points` 作为类成员变量，在每次调用 `evaluate_tour()` 函数时，将探索过的目标点添加到该变量中。然后在 `CumulativeGreedyCoverage` 类中，将所有巡游的 `visited_points` 汇总起来，即可得到所有已经探索过的目标点数量。具体实现如下：

class CumulativeGreedyCoverage(AbstractGreedyAndPrune):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.visited_points = set()
        
    def run(self):
        choice_dict = {}
        for ind_uav in range(self.nuavs):
            uav_residual_rounds = residual_ntours_to_assign[ind_uav]
            if uav_residual_rounds > 0:
                uav_tours = self.uavs_tours[ind_uav]
                for ind_tour in range(len(uav_tours)):
                    tour = uav_tours[ind_tour]
                    quality_tour = self.evaluate_tour(tour, uav_residual_rounds, self.visited_points)
                    choice_dict[quality_tour] = (ind_uav, ind_tour)
        best_value = max(choice_dict, key=int)
        return choice_dict[best_value], self.visited_points

    def evaluate_tour(self, tour : Tour, round_count : int, visited_points : set):
        new_points = set(tour.targets_indexes) - visited_points
        self.visited_points.update(new_points)
        return round_count * len(new_points)

在 `run()` 函数中，我们新增了一个变量 `self.visited_points` 来记录所有已经探索过的目标点，然后在 `evaluate_tour()` 函数中，我们将探索过的目标点添加到该变量中。最后，我们在 `run()` 函数中返回所有已经探索过的目标点数量。

可以在 `solution()` 方法中添加一个变量来记录已经探索过的目标点数量，然后在每次更新 `visited_points` 后更新这个变量。下面是修改后的代码：

    def __init__(self, aoi: AoI, uavs_tours: dict, max_rounds: int, debug: bool = True):

        self.nuavs = len(self.uavs)
        self.uavs_tours = {i: uavs_tours[self.uavs[i]] for i in range(self.nuavs)}
        self.__check_depots()
        self.reachable_points = self.__reachable_points()
        
    def __pruning(self, mr_solution: MultiRoundSolution) -> MultiRoundSolution:
        return utility.pruning_multiroundsolution(mr_solution)

        mrs_builder = MultiRoundSolutionBuilder(self.aoi)
        
        for uav in self.uavs:
            mrs_builder.add_drone(uav)
            
        residual_ntours_to_assign = {i : self.max_rounds for i in range(self.nuavs)}
        tour_to_assign = self.max_rounds * self.nuavs
        visited_points = set()
        explored_points = 0
        
        while not self.greedy_stop_condition(visited_points, tour_to_assign):
            itd_uav, ind_tour = self.local_optimal_choice(visited_points, residual_ntours_to_assign)
            residual_ntours_to_assign[itd_uav] -= 1
            tour_to_assign -= 1
            opt_tour = self.uavs_tours[itd_uav][ind_tour]
            new_points = set(opt_tour.targets_indexes) - visited_points
            explored_points += len(new_points)
