Iterative projection algorithms were studied for the convex feasibility problem. An algorithmic scheme was also proposed that generalizes both the string-averaging algorithm and the block-iterative projections (BIP) method with fixed blocks. The convergence of the string-averaging method in the inconsistent case was proved.
