Question

我目前正在研究强化学习问题，并且尝试将浮点哦继承类的另一个向量的vector<State>和vector<Action>中所添加的元素的位置增加，以便我可以操纵状态和行动的价值观。返回是在主要的另一个功能上，所以我不能使用它。我正在尝试使用this->，但无法正常工作。

Gradient.h

class Gradient: virtual public Sarsa
{
public:
    Gradient();
    Gradient(float w);

    //states with weights
    std::vector<float> StateWeights(float s, float l, float a);

    //from the actions vector will be created with weights 
    std::vector<float> ActionWeights(Action a);
    void IsStateActionSeen();

private:

    float w0,w1,w2,w3,w4,w5,w6;

    std::vector<float> state_action_weights;
    std::vector<float> StatesPos;
    std::vector<float> Actions;
};

Gradintent.cpp

//returns the possition and the values of state in floationg points
std::vector<float> Gradient::StateWeights(float s, float l, float a)
{   
    std::vector<float> StateW;
    //position of the state in the vector
    int x = Sarsa::StateisNow ( s,  l,  a);//here i take the values of the main to find which state is not
    float y = (float)(x);
    std::cout<<"State found: "<<x<<std::endl;
    //read the values of state from the position
    State st = all_states.at(x);
    std::cout<<"The State is: "<<st.get_pos()<<" "<<st.get_ang()<<" "<<st.get_spe()<<std::endl;
    //create a vector with the values of the state and the weights
    StateW={y, st.get_pos(),st.get_ang(),st.get_spe() };
    std::cout<<"The State is: "<<StateW.at(0)<<" "<<StateW.at(1)<<" "<<StateW.at(2)<<" "<<StateW.at(3)<<std::endl;
    this->StatesPos.push_back(&StateW);//i want to add it in the vector before it returns
    return StateW;//return to the main
}

错误：没有匹配的函数可以调用“ std :: vector :: push_back（std :: vector *）” this-> StatesPos.push_back（＆StateW）;

Answer 1

StatePos是float的向量，您只能push_back浮动（或将隐式转换为float的对象。

如果需要附加两个向量，则可以执行以下操作：

StatePos.insert( StatePos.end(), StateW.begin(), StateW.end() );

尝试将vector <float>推回到同一类的私有vector <float>中，而没有返回函数
