This is the app page of ODMO program for minimizing energy loss using GP

There are three main types of forest exploitation that are full exploitation, gradual exploitation, selected exploitation. We assume that the second method (gradual exploitaion) is chosen for exploiting the forest of S = km² in order to exploit and preserve the forest concurrently. Trees have to reach the size required before being chopped down which means they can be exploited after at least 4-year planting. The exploited area requested with aim to meet the total demand is km². The minimum area which have more-4-year-old trees is km². The minimum area exploited annually is km².
How to exploit this forest in 8 years to maximize the total old area? (xxxx need more describe)
