Fig. 3. Process overview and scheduling for a scenario. A scenario is initialized by loading the policies and distributional information for the stochastic parameters that characterize the scenario. For each run of the scenario, the stochastic parameters are sampled from their distribution. The annual loop runs the agent loop and also the landscape evaluators and the environmental processes independent of agent behavior, including the population and vegetation succession models. Note that the policy ranking index has two components: One depends on agent preference, and the other on current landscape valuations for ecosystem health and economics. The latter component is proportionately larger according to the magnitude of landscape deficiencies or scarcities. The effect of annual executions of the agent loop is tantamount to stochastic sequential optimization for ecosystem health and economics. An IDU is an integrated decision unit or a polygon in the landscape managed by an agent.
