In many cases where existence of solutions is guaranteed\, these solutions are not usually affordable in a direct way. Iterative methods (or algorithms)\, t herefore provide a convenient way of approximating these solutions. To a l arge extent\, most of these iterative methods can be traced to the popular gradient descent algorithm. This talk presents the prospects that may res ult in using a different approach\, and its usefulness even to equivalent reformulations of the nonlinear optimisation problem. Its applicability in some areas of science and technology is highlighted and a spectacular ap plication in radiotherapy treatment planning where algorithmic efficiency is especially required is demonstrated.\n\nThis work is Joint with Charles Ejike Chidume.\n LOCATION:https://researchseminars.org/talk/anpdews/15/ END:VEVENT END:VCALENDAR
