While the fixed problem is always a continuous model, it may contain a non-convex quadratic objective or non-convex quadratic constraints. As a result, it may still be solved using the MIP algorithm. Note An error is raised if the converted model contains more than one objective or scenario...

model.params.NonConvex = 2 ahead of the codes: opt = SolverFactory("gurobi", solver_io="python") opt.solve(model, tee=True) But then it says: "AttributeError: 'ConcreteModel' object has no attribute 'params'". How can I set the NonConvex parameters to 2 to run the model?
Gurobi 运行时提示 “Objective Q not PSD (diagonal adjustment of 1.0e+01 would be required). Set NonConvex parameter to 2 to solve model.”参考:gurobi 9.0 新功能 整数规划/混合整数规划问题评价准则: 百分比界差 Gap(f(x))=\frac{OPT-LP}{LP}\\ OPT 为当前的最优解,LP 为去掉整数约東后的...
Non-Convex Quadratic Optimization Webinar Summary One major new feature in Gurobi 9.0 is a new bilinear solver, which allows users to solve problems with non-convex quadratic objectives and constraints (i.e., QPs, QCPs, MIQPs, and MIQCPs). Many non-linear optimization solvers search for local...
