Nonsmooth nonconvex global optimization in a Banach space with a basis

Following paper [1), significant improvements are proposed as concerns the class of problems that can be solved, the quality of the solution, and the numerical implementability of the method. Optimization is considered in a Banach space over a nonconvex inf-compact, finitely infrobust set for a multivalued nonconvex continuous functional. The iterative method is monotonic and represents generalized variant o£ setwise descent onto the set of all global minimizers. A real-life example of the vertical soft landing of an aircraft is considered to illustrate the method.
