1 简介
平衡 优 化 器 ( equilibrium optimizer，EO) 是 Afshin Faramarzi 等人于 2019 年提出的一种新型智能算法，并在多个测试函数上相对传统智能算法表现出较好的优越性。

% fobj = @YourCostFunction
% dim = number of your variables
% Max_iteration = maximum number of iterations
% Particles_no = number of particles (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
