. The quadratic representation of the objective function is the two function of the independent variable.Well, since it is a convex two-time planning problem, the optimal solution can be obtained through some of the optimized tools of QP (quadratic programming). So, our problem is solved at this point. Although this problem is really a standard QP problem, but it also has its special structure, through the Lagrange duality transformation to the dual

　One of the most notable changes in the 2014 was that the two-live data center spanned the conceptual hype and was accepted by many business users. HDS presents a new dual-live mode--gad (Global-active Device), which provides a solid guarantee for business continuity by enabling dual-live storage.Today, 7x24-hour business continuity and data access is no longer a "patent" for large enterprise customers, but

first of all, if the knowledge of some operating systems is not very familiar, and do not have too much time, it is recommended not to try to install a dual system, although there are many online installation of dual-system tutorials, but everyone's situation is different, for beginners, the hole here is too deep. If you really want to install a dual system, you
