two so action two is going to pick up a triangle the triangle the picking up of a triangle means that our pi for this step or sorry our five for the step is going to be zero one okay so our successor features this is not the features itself this is the successor features the successor features decompose into the next step plus all the next steps that we can follow okay so all the steps that will come so what are these features going to be is it's going to be the sum over that plus everything that follows and i can take a little bit of a guess
