摘要
针对分裂可行性问题,在自适应步长球松弛CQ算法基础上引入惯性项,加快算法的收敛速度;同时,利用Halpern迭代格式调整算法,并证明算法在无限维Hilbert空间中强收敛。
Aiming at the split feasibility problem,an inertial term is added into the ball-relaxed CQ algorithm with self-adaptive stepsize in order to accelerate the convergence rate.Meanwhile,the algorithm is adjusted according to Halpern iteration structure.Finally,strong convergence of the current algorithm is proved in infinite-dimensional Hilbert space.
