The Strong Convergence of Ishikawa Iterative Sequence for Gradient Projection Operators

n order to prove our desired result, an Ishikawa iterative CQ deformation is first worked out for the Gradient projection operator, and the strong convergence of which is then proved. And a viscous deformation in Ishikawa form is presented. In combination with certain suitable conditions, the strong convergence of the gradient projection operators is proved, and the results obtained greatly improve the results published in the latest literatures.
