Further insight into the possible changes in energies arises from the nature of the constraints involved in a structure . The system utilized the many constraints involved in the class scheduling process to solve the problem . In particular , it is important to identify any generic properties , mechanisms or constraints involved in the maintenance , evolution , generation or loss of biodiversity . After a series of discussions , they understood the constraints involved in site selection , the options available , and why the site was chosen .
