对于moea_demo3中的例子,我尝试用aimFunc改写,但是始终显示Objv不合法,经过检查我的objv1、objv2和Objv都是符合要求的,他们分别为:(30,),(30,),(30,2) ,下面是我改写的:

    def aimFunc(self, pop):
        print(pop.sizes)
        vars = pop.Phen.astype(int)
        Objv1 = np.sum(self.P[vars,[0, 1, 2, 3, 4]],axis=1)
        Objv2 = np.sum(self.R[vars,[0, 1, 2, 3, 4]],axis=1)
        print(Objv1.shape)  # 应该是 (NIND,)
        print(Objv2.shape)  # 应该是 (NIND,)
        pop.CV = np.sum(self.C[vars,[0, 1, 2, 3, 4]],axis=1).T - 92
        pop.Objv = np.vstack([Objv1,Objv2]).T
        print(pop.CV.shape)  # 应该是 (NIND,)
        print(pop.Objv.shape)  # 应该是 (NIND,2)

我的种群数设置的是30,调用的模板是NSGA-II

这是demo用evalVars写的:

    def evalVars(self, Vars):  # 目标函数
        x = Vars.astype(int)
        f1 = np.sum(self.P[x, [0, 1, 2, 3, 4]], 1)
        f2 = np.sum(self.R[x, [0, 1, 2, 3, 4]], 1)
        print(f1.shape)
        print(f2.shape)
        # 采用可行性法则处理约束
        CV = np.array([np.sum(self.C[x, [0, 1, 2, 3, 4]], 1)]).T - 92
        ObjV = np.vstack([f1, f2]).T
        print(CV.shape)
        print(ObjV.shape)
        return ObjV, CV

两者似乎没什么区别,可为什么用aimFunc就不合法呢

好吧,不用回复了,是ObjV中V被写成了小写
