TY - JOUR ID - eprints1703 UR - http://nonlinearstudies.com/index.php/mesa/article/view/403 JF - Mathematics in Engineering, Science and Aerospace (MESA) Y1 - 2010/// SP - 303 IS - 3 VL - 1 N2 - Functional optimization is investigated using tools from information-based complexity. In such optimization problems, a functional has to be minimized with respect to admissible solutions belonging to an infinite-dimensional space of functions. This context models tasks arising in optimal control, systems identification, machine learning, time-series analysis, etc. The solution via variable-basis approximation schemes, which provide a sequence of nonlinear programming problems approximating the original functional one, is considered. Also for such problems, the information complexity is estimated.
