③'gurobi.NonConvex', 2非半正定模型未设置(注释:ops.gurobi.NonConvex=2也行) 后来无意间发现,是gurobi需要写成gurobi+才行,gurobi+的意思是优先使用gurobi。不添加+号就会出现model等于空集,导致无法将后续的冲突约束导出。(这点,未见有博客明确指出,较为隐晦,我已经一一验证以上四点,发现就是gurobi+的原因,与...
gurobi是由美国Gurobi公司开发的新一代大规模数学规划优化器,在 Decision Tree for Optimization Software 网站举行的第三方优化器评估中,展示出更快的优化速度和精度,成为优化器领域的新翘楚。 官网链接:https://www.gurobi.com/ 用edu邮箱注册,可申请学术license,很方便。 软件下载:https://www.gurobi.com/download...
[model,recoverymodel] = export(C,OBJ,ops); %导出所有约束模型 iis = gurobi_iis(model); %查看约束冲突的序号 gurobi_write(model, 'TestModel.lp');%根据约束冲突的序号找变量名,进而从m文件中找出约束 进阶: sum(iis.Arows) %统计约束冲突的个数 find(iis.Arows==1)-1 %在命令行窗口展现冲突约...
One reason might be different tolerances used by Gurobi and the built-in Matlab solver. Another reason might be that the two models you solve are slightly different. You could write your model to a human-readable LP file via the gurobi_write() function. You can open the file w...
Currently I wanna run the programming like: min{ x*Mx+mx} s.t. A0*x=b0; A1*x<b1. and my code about Gurobi parts as follows: %Gurobi Define for i=1:8*N model.varnames{i} = sprintf('x[%d]',i); end model.Q = sparse(M); ...
ops = sdpsettings('solver', 'gurobi', 'verbose', 2, 'debug', 1); F = sum(P_PV*C_PV+C_buy*P_buy); result = optimize(C,F,ops); if result.problem == 0 % problem =0 代表求解成功 disp(value(F)); else disp('求解出错'); ...
