estimate the value of the intermediate nodes using this v model from over here um i have v s v was green so they use this v model from over here to estimate at a certain depth so v learns to look into the future so everything that can happen from here and it estimates and it says well from here you maybe have a you know a 0.5 value or maybe a negative 0.7 and so on so v learns to assign these values to situations to states which are these nodes right here and p learns to suggest things to expand that's alpha zero
