Fibonacci method is an optimization method which can be used to find optimum of a 1D function (even discrete function) using elimination method. For use this method the initial interval of uncertainty, in which the optimum lies, has to be known. In addition the objective function should be unimodal, which has just an optimum solution in initial interval.
