A method of constructing a database-free optimal dynamical system and the global optimal dynamical system

摘要

In this paper, to overcome the drawbacks of POT which minimize the reminder, not only the optimal functional with minimal residual is put forward, but also the method of global optimization is used. Under the condition of large reminder. The optimal bases can also be obtained through the method of POTres without the approaching, of initial conditions, In addition, compared with local optimization, the advantage of global optimization is remarkably. On the one hand, the global optimal bases include more information than the local optimal bastes. On the other hand, from the point of error, the global optimal bases independent of the object functional and the initial bases.
