abstract = {<p style="text-align: justify;">In this paper, we apply stochastic Galerkin finite element methods to the optimal
control problem governed by an elliptic integral-differential PDEs with random field. The
control problem has the control constraints of obstacle type. A new gradient algorithm
based on the pre-conditioner conjugate gradient algorithm (PCG) is developed for this
optimal control problem. This algorithm can transform a part of the state equation matrix
and co-state equation matrix into block diagonal matrix and then solve the optimal control
systems iteratively. The proof of convergence for this algorithm is also discussed. Finally
numerical examples of a medial size are presented to illustrate our theoretical results.</p>},
