Improved krill algorithm and its application in structural optimization
In this paper,the standard krill algorithm(KH)has the disadvantages of slow convergence speed,insufficient calculation accuracy and easy to fall into local optimal solution for complex problems,an improved krill algorithm(SDEKH)which combines improved differential evolution operator and S-type adaptive inertia weight is proposed in this paper.Through a variety of standard test functions to compare and test a variety of intelligent algorithms such as SDEKH and KH,the excellent performance of SDEKH is verified,and SDEKH is used to optimize the truss structure,and the optimization results of SDEKH are compared with other methods to verify that the optimization efficiency and accuracy are improved,which provides a more efficient and accurate method for engineering structure optimization design.
