Optimal external estimation of solution sets of interval systems of equations. Part 1.

A new class of adaptive and sequentially guaranteeing (parameter partitioning methods) (PPS-methods) for computing optimal (exact) component-wise bounds of the solution sets to interval linear systems of equations is presented. A possible generalization of the new technique to the general nonlinear case is considered. The results of numerical calculations and the comparison to other known approaches for solving the given problem are presented.
