【Abstract】 The methods for discrete variable optimization are reviewed,which are classified into traditional methods and modern methods. Some methods are described such as rounding－ off, relative difference quotient, simulated annealing, genetic and Tabu search algorithm. The problems such as“ the singular solution of structural optimization” for topological optimization are mentioned and the solving methods for this problem are described.更多还原
