1 简介
海洋捕食者算法 ( Marine Predators Algorithm，MPA) 是Afshin Faramarzi 等人于 2020 年提出的一种新型元启发式优化算法.

% fobj = @YourCostFunction
% dim = number of your variables
% Max_iteration = maximum number of iterations
% SearchAgents_no = number of search agents
% lb=[lb1,lb2,...,lbn] where lbn is the lower bound of variable n
% ub=[ub1,ub2,...,ubn] where ubn is the upper bound of variable n

display(['The best optimal value of the objective function found by MPA is : ', num2str(Best_score,10)]);
disp(sprintf('--------------------------------------'));
img =gcf; %获取当前画图的句柄
print(img, '-dpng', '-r600', './运行结果.png') %即可得到对应格式和期望dpi的图像
