A novel hybrid differential evolution and symbiotic organisms search algorithm for size and shape optimization of truss structures under multiple frequency constraints

作者：

Highlights：

• A novel hybrid differential evolution and symbiotic organisms search (HDS) is suggested.

• This HDS is crossbred between differential evolution (DE) and symbiotic organisms search (SOS).

• The HDS yields high-quality optimal solutions with a lower computational effort.

• 26 mathematical functions along with 5 examples of shape and size truss optimization are tested.
