This e-book provides effects at the convergence habit of algorithms that are often called important instruments for fixing convex feasibility difficulties and customary mounted aspect difficulties. the most aim for us in facing a identified computational errors is to discover what approximate answer will be bought and the way many iterates one must locate it. in accordance with be aware of effects, those algorithms should still converge to an answer. during this exposition, those algorithms are studied, making an allowance for computational blunders which stay constant in perform. for that reason the convergence to an answer doesn't occur. We express that our algorithms generate an excellent approximate answer if computational mistakes are bounded from above via a small optimistic consistent.

Beginning with an advent, this monograph strikes directly to study:

· dynamic string-averaging tools for universal mounted element difficulties in a Hilbert area

· dynamic string equipment for universal fastened aspect difficulties in a metric space<

· dynamic string-averaging model of the proximal algorithm

· universal fastened aspect difficulties in metric spaces

· universal fastened aspect difficulties within the areas with distances of the Bregman type

· a proximal set of rules for locating a typical 0 of a relatives of maximal monotone operators

· subgradient projections algorithms for convex feasibility difficulties in Hilbert areas

Our main goal is to obtain an approximate solution of the problem in the presence of computational errors. We show that the iterative method generates a good approximate solution, if the sequence of computational errors is bounded from above by a constant. Moreover, for a known computational error, we find out what an approximate solution can be obtained and how many iterates one needs for this.
