Recently, energy saving problem attracts increasingly attention from researchers.
Yu et al. [37] formulate the C-RAN energy saving problem as a joint resource provisioning problem.
Indeed, even with a simplifying assumption of the worst-case interference, the energy saving problem is a mixed integer programming problem that is strongly related to the bin-packing problem, which in turn is known to be NP-hard.
Facebook may have already been building a solution to the content saving problem, and figured there was no need to buy Spool's version when its own was in the works.
For many people, being asked to solve their own retirement savings problems is like being asked to build their own cars.
"You can't invest your way out of a savings problem," Mr. Utkus warned.
Lankov added: "The North Koreans have always known what China thinks of them, but it might become a face-saving problem if they feel they have to show their displeasure".
The next section formulates the energy savings problem in the PCC mathematically and introduces a heuristic algorithm to solve it.
The next section introduces the mathematical framing of the energy savings problem and the proposed heuristic algorithm to solve it.
In this context, a host of research work has been conducted in order to propose a wide range of solutions to the energy-saving problem.
