Optimization is performed over all implementable and feasible policies. Such initiatives have made the implementation of highly innovative concepts and ideas easily implementable. Applications are implementable as deployable packages and are procurable in the system market place. Still other work is less theoretical by attempting to compare implementable schemes. The committee developed four areas of recommendations, with twenty specific proposals for implementable actions. Being relatively simple, the model is readily implementable in computer software (including a spreadsheet). The laws must also be practical and implementable over a long period of time. Therefore, Maymin's lambda-q calculus is probably not implementable on a physical device . Neither idea was practically implementable in da Vinci's time. An advantage of the design is that they are implementable on a global level.
