Cyclic subgradient projections

Yair Censor, Arnold Lent

Research output: Contribution to journalArticlepeer-review


A cyclically controlled method of subgradient projections (CSP) for the convex feasibility problem of solving convex inequalities is presented. The features of this method make it an efficient tool in handling huge and sparse problems. A particular application to an image reconstruction problem of emission computerized tomography is mentioned.
