    Evolutionary optimization with active learning of surrogate models and fixed evaluation batch size

  • Original language description

    Evolutionary optimization is often applied to problems, where simulations or experiments used as the fit ness function are expensive to run. In such cases, surro gate models are used to reduce the number of fitness eval uations. Some of the problems alsorequire a fixed size batch of solutions to be evaluated at a time. Traditional methods of selecting individuals for true evaluation to im prove the surrogate model either require individual points to be evaluated, or couple the batch size with the EA gener ation size. We propose a queue based method for individual selection based on active learning of a kriging model. Indi viduals are selected using the confidence intervals predicted by the model, added to a queue and evaluated once the queue length reaches the batch size. The method was tested on several standard benchmark problems. Results show that the proposed algorithm is able to achieve a solution using significantly less evaluations of the true fitness function.
