Abstract :
The paper addresses the practical problem of reducing the number of necessary function calls involving time consuming finite-element solutions by combining various evolution techniques with approximation methods based on Response Surface Methodology. A new algorithm is proposed which offers significant improvement of performance while preserving the quality of the final result. Comparisons are made between the new algorithm and different standard strategies in terms of reliability, efficiency and cost
