    forming a transition matrix based at least in part on the account data and the plurality of account states;

    generating a Markov Decision Process (MDP) model based at least in part on the transition matrix;

    using the Markov Decision Process model to determine a change in the at least one control variable resulting in a desired effect on the plurality of account states; and
