This study proposes a novel strength of multi-objective gravitational search algorithm and
bat algorithm MOGSABAT to solve multi-objective optimisation problem. The proposed
MOGSABAT algorithm is divided into three stages. In the first stage (moving space), a switch
in a solution from single function to multiple functions that contain more than one objective to
use the gravitational search algorithm GSA is determined. We established a new equation to
calculate the masses of individuals in the population using the theoretical work found in the …
