Moreover, when the LSF is expressed by implicit partial differential equations (PDEs), it leads to computational difficulties. The surrogate method, i.e., metamodel, is capable of replacing complex physical models by simple mathematical models, which aims to solve complex problems with high ...

A general method using multipliers for finding the conserved integrals admitted by any given partial differential equation (PDE) or system of partial differential equations is reviewed and further developed in several ways. Multipliers are expressions wh

On the other hand, implicit ODE- and partial differential equation-based models17,29,30,31 can be beneficial in solving continuously defined physics problems and control tasks. Moreover, for generative modelling, continuous normalizing flows built by ODEs are the suitable choice of model as they ...
The strong form formulation uses the partially differential equation, while the weak form solution is based on a variational method or a weighted residual method. The MLS approximation of unknown vector UkI is defined at point I as in [37]: (19)UkI=[ΦI]{Ukm} where [ΦI] is the matrix...

stand for partial derivative. Now, the procedures of this approach are described below: Procedure I: Initially, first we need to turn the attached partial differential equation into the form of an ordinary differential equation (ODE). To accom- plish this, we define a new variable w as the...
We consider the initial-boundary value problem for the degenerate parabolic equation ut=∇⋅(f(u)∇u+g(u,x,t)),x∈Ω, t>0 in a smooth bounded domain Ω⊂RN(N∈N) under the no-flux boundary condition with a non-negative initial data u0∈L∞(Ω). Here f is a non-negativ...
