代码说明:

% 该算法通过a = x-r*cos(angle),b = y-r*sin(angle)将圆图像中的边缘点% 映射到参数空间(a,b,r)中,由于是数字图像且采取极坐标,angle和r都取% 一定的范围和步长,这样通过两重循环(angle循环和r循环)即可将原图像% 空间的点映射到参数空间中,再在参数空间(即一个由许多小立方体组成的% 大立方体)中寻找圆心,然后求出半径坐标。

    This work proposes two novel optimization algorithms called Salp Swarm Algorithm (SSA) and Multiobjective Salp Swarm Algorithm (MSSA) for solving optimization problems with single and multiple objectives. The main inspiration of SSA and MSSA is the swarming behaviour of salps when navigating and foraging in oceans. These two algorithms are tested on several mathematical optimization functions to observe and confirm their effective behaviours in finding the optimal solutions for optimization problems.
