Abstract
For (equation omitted) be an ordered <TEX>$\ell$</TEX>(t)-tuple of numbers in{1,2, …,<TEX>$\ell$</TEX>}and let Tt be chosen from a finite composition of orthogonal projections (equation omitted) acting on the normed linear space <TEX>$C_1$</TEX>(X) to closed convex subset <TEX>$S(fi_{j}\;^{t})$</TEX> respectively. In this paper, we study the convergence of the sequence (equation omitted) where (equation omitted).
