Claim 17:
18. The storage media of claim 14, wherein the training the online state value network based on vehicle states of the plurality of vehicles before and after the dispatching and rewards associated with the dispatching comprises:
for each of the plurality of vehicles:
determining a first vehicle state value using the online state value network based on the vehicle state before the dispatching;
determining a second vehicle state value using the online state value network based on the vehicle state after the dispatching; and
determining a temporal difference (TD) error based on the first vehicle state value, the second vehicle state value, and a reward associated with the dispatching;

constructing an objective function based on the plurality of TD errors; and
updating parameters of the online state value network using gradient descent to minimize the objective function.
