Abstract: | Given a real function f of class
defined on the unit cube In=0,1]n , n ≥ 2, our purpose consists in finding an algorithm to approximate to
by a dimensional reduction. The method deals with α-dense curves γα in the domain In with arbitrary small density α and a minimization-preserving operator T (briefly M.P.O.) applied to the univariable function
By reiterating the action of this M.P.O. we obtain an algorithm to determine a global minimizer t0* of fα. The value fα(t0*), taken as an approximation to f*, only depends on the density α of the curve chosen to densify the domain of the objective function. |
