In this paper, the optimal control problem of parabolic integro-differential equations is solved by gradient recovery based two-grid finite element method. Piecewise linear functions are used to ...

Abstract: This letter studies the synthesis of an active perception policy that maximizes the information leakage of the initial state in a stochastic system modeled as a hidden Markov model (HMM).

Abstract: This article aims at proposing a multisystem gradient method (MSGM) for solving the integrated nonlinear optimal control problem with multiple systems and unspecified terminal time. This ...

Least-squares reverse-time migration (LSRTM) can overcome the problems of low resolution and unbalanced amplitude energy of deep formation imaging in reverse-time migration (RTM); hence, it can obtain ...

Interpreting gradient methods as fixed-point iterations, we provide a detailed analysis of those methods for minimizing convex objective functions. Due to their conceptual and algorithmic simplicity, ...

What is Conjugate-Gradient(CG)-Method? Iterative method for solving large systems of linear equations. CG is effective for systems of the form Ax = b where x is an unknown vector, b is a known vector, ...
