A diagonal finite element-projection-proximal gradient algorithm for elliptic optimal control problem

A diagonal finite element-projection-proximal gradient (DFE-P-PG) algorithm and its accelerated forms for elliptic optimal control problem with L1-control cost are proposed in this paper. Firstly, the elliptic optimal control problem is discretized by the diagonal finite element method (DFEM). Then...
