“…It uses Peano type space-filling curves (see [2,5,26,38,42] for examples of usage of space-filling curves in mathematical programming) to reduce the original Lipschitz multi-dimensional problem to a Hölder univariate one (a comprehensive presentation of this approach can be found in [42]). Global optimization of Hölder functions (see [9,19,45]) has given new tools for solving the reduced one-dimensional problem. Peano curves avoid constructions of support (or auxiliary) functions usually used in the multi-dimensional Lipschitz optimization (see, for example, [15,17,18,25,27,42] and references given therein).…”
