At first, convex functions are always defined on a domain which is a convex set. An illustrative way to present a convex set is by using a two-dimensional example of plotting. Let us visualize the key property: in a convex two-dimensional area C⊆ℜ2, you can touch any pair x1,x...
"I...applied a pattern search algorithm in Global Optimization Toolbox to optimize for factors such as throughput, required production equipment, manpower, and waste. It would take thousands of experiments to assess all possible model variants. I could achieve the same results with a fraction of...
In addition, conventional NWP algorithms largely rely on parameterization, which uses approximate functions to capture unresolved processes, where errors can be introduced by approximation8,9. The rapid development of deep learning10 has introduced a promising direction, which the scientific community ...
gradient information and has a comparative advantage in handling large models such as ours.Footnote13The three pillars of successfully applying the solver to a non-linear problem are the initial values, scaling, and bounds. Furthermore, the solver is designed to operate with smooth functions only,...

We start from the simple Boussinesq approximation of the primitive equations of the ocean51,84 and use the Hamiltonian formalism of ref. 43. Assuming hydrostatic balance, the dispersion relation of internal waves is given by $${\omega }^{2}={f}^{2}+\frac{{g}^{2}}{{\rho }^{2}{N...
The second key issue revolves around improving SMA's global exploration during the pre-middle stage to effectively search for a specific spatial location and achieve a more comprehensive approximation of the global solution. The introduction of an appropriate variable is crucial to address this problem...
The key point of the proof depends on the structure of the perturbation system by means of a suitable initial approximation function of the Nash-Moser iteration scheme. Keywords: Boussinesq system; global Sobolev solution; Nash-Moser iteration scheme MSC 2010: 35Q31; 35A01 1 Introduction and ...
