I am trying to maximize an efficiency function which is fractional in nature, through power allocation. It is already known that the function has an uni modal behavior with respect to power allocated. In this case, should I go for Dinkelbach's method of first converting it into a convex function and then optimize or can I go for other search methods(both direct and indirect ) to locate the peak value? Most papers (almost all) have tackled these types of problem by Dinkelbach's method. Some body please suggest a soution
