Evolutionary Algorithms (EAs) are non-derivative-based and stochastic op timization methods which simulate the natural evolution process. A type of EA, Derandomized Evolution Strategy (DES) is applied to the time-invariant (9 decision variables) and time-varying (54 decision variables) optimal design of groundwater bioremediation. DES shows good computational efficiency and accuracy for both the cases, even though it does not use derivative information.
