报告摘要：

An alternating direction method ofmultipliers (ADMM) is proposed for solving the elliptic equation optimal controlproblem. The unconstrained as well as Box-constrained cases of the Dirichletboundary control, Robin boundary control, and right hand side control problemsare considered here. A finite element method is applied to approximate thestate variable and the control variable, then the continuous optimal controlproblem is discretized into a finite dimensional one. Based on the separable structure,ADMM is applied to solve the discretized system. The global convergence analysisis established, which includes the discretization error by the finite elementand the iterative error by ADMM. Finally, numerical simulations are presentedto verify the efficiency of the proposed algorithm.
