【Abstract】 The structural optimization technique was briefly described. The basic principle of neural-network-based complex-structure optimization design was introduced. A simulated annealing algorithm was given to solve neural network-based complex-structure optimization design. Two examples were given to illustrate the efficiency of the given method. This method is more effective and accurate than other optimization methods.更多还原
