The Improved Slime Mould Algorithm with Cosine Controlling Parameters

Abstract

Along with the fact that the problems we human met are becoming more complicated and complex, and more variables are involved, the new proposed algorithms would embrace more controlling parameters. However, not all of the controlling equations involved initially are satisfactory. Considering the ongoing runtime errors/warnings occurred in the program of a newly raised slime mould algorithm (SMA), we hence propose a replacement by the cosine function, which would produce a similar and slow-change for the controlling parameters. And it also met all of the values in the definitional domain. Simulations experiments were carried out and results proved that the improved SMA with cosine controlling parameters could not only eliminate the ongoing warnings/errors, it could also perform better in optimization.
