A nonmonotone spectral projected gradient method for large-scale topology optimization problems
A nonmonotone spectral projected gradient method for large-scale topology optimization problems
An efficient gradient-based method to solve the volume constrained topology optimization problems is presented. Each iterate of this algorithm is obtained by the projection of a Barzilai-Borwein step onto the feasible set consisting of box and one linear constraints (volume constraint). To ensure the global convergence, an adaptive nonmonotone line …
