Tīmeklis2024. gada 3. febr. · Each Lagrangian problem is providing an upper bound, the Lagrangian Dual consists in finding the best one, solving the problem (D): The dual problem (D) above also has a nice set of properties: TīmeklisLagrangian, we can view a constrained optimization problem as a game between two players: one player controls the original variables and tries to minimize the Lagrangian, while the other controls the multipliers and tries to maximize the Lagrangian. If the constrained optimization problem is well-posed (that is, has a finite
TīmeklisIn the field of mathematical optimization, Lagrangian relaxation is a relaxation method which approximates a difficult problem of constrained optimization by a simpler … TīmeklisThe objective of this paper is to investigate a multi-objective linear quadratic Gaussian (LQG) control problem. Specifically, we examine an optimal control problem that minimizes a quadratic cost over a finite time horizon for linear stochastic systems subject to control energy constraints. To tackle this problem, we propose an efficient …
