Design Informatics has three points of view. First point is the efficient exploration in design space using evolutionary computation. Second point is the structuring and visualizing of design space using data mining. Third point is the application to practical problems. The investigation of efficient evolutionary-based optimizer for the above first point is essential in order to generate hypothetical database for data mining. In the present study, the performance regarding diversity and convergence has been compared among pure and their hybrid methods using three standard mathematical test problems with/without noise. The result indicates that the hybrid method between the genetic algorithm based on the elitist non-dominated sorting genetic algorithm and the differential evolution is better performance for efficient exploration in the design space under the condition for large-scale engineering design problems within 10<SUP>2</SUP> order evolution at most. Moreover, the comparison among eight crossover indicates that the principal component analysis blended crossover is good performance on the hybrid method between the genetic algorithm and the differential evolution.
