Improved Error Estimate for an Implicit Discretization Scheme for Linear-Quadratic Control Problems We analyze an implicit discretization scheme for a class of linear-quadratic optimal control problems without mixed state-control terms. Under the assumption that the optimal control has bang-bang structure we show convergence of the discrete approximation and improve existing error estimates to order ..作者: GROWL 時間: 2025-3-22 15:36

Soliton Solutions as Inverse Problem for Coefficient Identificationormulate the bifurcation problem, introducing a new parameter; and in such a way we expel the trivial solution of the original problem. The Method of Variational Imbedding (MVI) is used for solving the inverse problem. We illustrate the approach by comparing the numerical solution with a known exact solution of the Boussinesq equation.作者: 雪白 時間: 2025-3-23 12:58 作者: Cocker 時間: 2025-3-23 17:02
