The stochastic convex feasibility problem (SCFP) is theproblem of findingalmost common points of measurable families of closed convex subsets inreflexive and separable Banach spaces. In this paper we prove convergencecriteria for two iterative algorithms devised to solve SCFPs. To do that, wefirst analyze the concepts of Bregman projection and Bregman function withemphasis on the properties of their local moduli of convexity. The areas ofapplicability of the algorithms we present include optimization problems,linear operator equations, inverse problems, etc., which can be representedas SCFPs and solved as such. Examples showing how these algorithms can beimplemented are also given.
