pareto前沿图
原项目在绘制3维帕累托前沿图时使用
self.ax = Axes3D(self.fig)创建绘图区域，但是在目前较高版本中已被弃用，绘制出的3维pareto前沿图空白，而修改为self.ax = self.fig.add_subplot(111, projection='3d')可以正常绘制，如下图所示pareto解集中存在重复解
本人在使用
moea_NSGA2_templet进行多目标问题求解时最终求得的pareto解集中总是会出现重复解，且各个解顺序杂乱，不利于作出决策图中两个解的值完全一样(包括后面精确到所有位数)，并且随着种群大小、迭代次数的增多，重复解个数会越来越多
本人通过
NDSet = NDSet[np.unique(NDSet.ObjV,return_index=True,axis=0)[1]]对重复解进行排除，并且各个解按照大小顺序排列
