Finally, those solutions which have highest% return and lowest risk, would be considers as a vector called efficient frontier.% Normally, portfolio solves by traditional methods such as mean-variance, mean semi% variance, and mean absolute deviation but not always guaranteed the best solution.c;clear;close all;%% Run Appdataload(mydata);Rdata.R;nAssetsize(R,2);MinRetmin(mean(R,1));MaxRetmax(mean(R,1));nSol10;DRlinspace(MinRet,MaxRet,nSol);model.RR;model.methodcvar;model.alpha0.95;Wzeros(nSol,nAsset);WReturnzeros(nSol,1);WRiskzeros(nSol,1);for k1:nSolmodel.DesiredRetDR(k);disp([Running for Solution # num2str(k) :]);%-----------------------------------out RunWDOA(model);%-----------------------------------disp(__________________________);disp();W(k,:)out.BestSol.Out.w;WReturn(k)out.BestSol.Out.ret;WRisk(k)out.BestSol.Out.rsk;endEFfind(~IsDominated(WRisk,WReturn));%% Resultsfigure;plot(WRisk,WReturn,y,LineWidth,2);hold on;plot(WRisk(EF),WReturn(EF),r,LineWidth,4);legend(,Efficient Frontier);ax gca;ax.FontSize 14;ax.FontWeightbold;set(gca,Color,w)grid on;xlabel(Risk);ylabel(Return);figure;plot(out.BestCost,k, LineWidth, 2);xlabel(ITR);ylabel(Cost Value);ax gca;ax.FontSize 14;ax.FontWeightbold;set(gca,Color,c)grid on;out.BestSol.Out⛄ 运行结果​⛄ 参考文献Weevil damage optimization algorithm and its applications❤️ 关注我领取海量amatlab电子书和数学建模资料❤️部分理论引用网络文献若有侵权联系博主删除
