If recording is enabled the traversal of the computational graph of each expression is started as soon as it occurs on the right-hand side in a statement. Note that the partial derivatives are only stored if the corresponding argument has some dependency on the input variables set by the user. This kind of dependency or activity tracking is relatively easy to accomplish since every variable stores an index along with its value. A zero index represents passive variables while a non-zero index identifies active variables.
