In this paper, a new hybrid evolutionary-gradient algorithm is proposed to solve global numerical problems of topology optimization. The proposed algorithm is developed as a compromise between the direct and gradient-based optimization approaches. A short comparative study of computational results demonstrates the validity of the proposed method, as well as the necessity of its use.

W niniejszej pracy zaproponowano nowy, hybrydowy algorytm gradientowo-ewolucyjny do numerycznego rozwiązywania zagadnień z zakresu globalnej optymalizacji topologii. Proponowany algorytm stanowi kompromis między bezpośrednimi i gradientowymi metodami optymalizacji. Krótka analiza porównawcza wyników obliczeń wykazuje walidację proponowanej metody, a także konieczność jej stosowania.
