1. Consider your real production
In the early years of the project you will find a lot of concerns and the most value in terms of NPV. Knowing that, we decide to consider a 10-year surface to optimize the first 5 years. By an obvious assumption, as the surface used corresponds to a decade, it will contain the interval from the 1st to 5th period and represents a lot more mass. However, this simple input can restrict the space where the algorithm has to find a solution which could reduce the run time and help it to deliver better results respecting the set of constraints given.
