多节优化器（Multi-Verse Optimizer (MVO) ）解决单目标优化问题

Posted 2021-08-17 这是一个很随便的名字

【Matlab源码】

 

Multi-Verse Optimizer (MVO) 的 灵感来源于 宇宙学中的三个概念：白洞、黑洞和虫洞。开发这三个概念的数学模型分别用于执行探索、开发和局部搜索。

MVO 旨在解决单目标优化问题。

代码：

% You can simply define your cost in a seperate file and load its handle to fobj 
% The initial parameters that you need are:
%__________________________________________
% fobj = @YourCostFunction
% dim = number of your variables
% Max_iteration = maximum number of generations
% 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
% If all the variables have equal lower bound you can just
% define lb and ub as two single number numbers

% To run MVO: [Best_score,Best_pos,cg_curve]=MVO(Universes_no,Max_iteration,lb,ub,dim,fobj)
%__________________________________________

Universes_no=60; %Number of search agents (universes)

Max_iteration=500; %Maximum numbef of iterations

[Best_score,Best_pos,cg_curve]=MVO(Universes_no,Max_iteration,lb,ub,dim,fobj);
