Golden section search is a part of unconstrained nonlinear optimization for strictly unimodal functions. This method is used to find a minimum or maximum by narrowing values in a specific interval. The extrema exists in the range. Based on the unimodal function, we assume that the local extrema is simultaneously the global extrema. In this method we do not use derivation, but rather a "step-by-step" approximation to the extrema.
