Optimal design of truss structures for size and shape with frequency constraints using a collaborative optimization strategy

作者：

Highlights：

• A collaborative parallel optimization strategy is proposed.

• A higher-level TLBO algorithm called school-based optimization is developed.

• Size and shape optimization under frequency constraints is addressed.

• Comparative studies illustrate the superiority of the proposed algorithm.
