Description
Summary:In this paper, a novel optimization algorithm, named group search optimizer (GSO), is used to truss structure topology optimization. The group search optimizer is improved in two aspects which including using harmony memory and adhering to the boundary. Two topology methods, such as heuristic topology and discretization of topology variables, are incorporated with GSO to make sure that the topology optimization works well. In the end of the paper, two numerical examples were used to test the improved GSO. Calculation results show that the improved GSO is feasible and robust for truss topology optimization.
