Here's the message of infeasible model (when 'presolve' parameter is set to 0): Nodes    |    Current Node    |     Objective Bounds      |     Work Expl Unexpl |  Obj  Depth IntInf | Incumbent    ...

The programme is weitten in Matlab with yalmip.Here are some details: I have linearized two items of two variables multiplication in order to avoid quardratic models as follows,the result is the li...

Hi Matthias, I've followed your advice and also revised some constraints.Now the model seem to be able to run but new problems emerge: Warning: max constraint violation (7.9532e-01) exceeds toleran...

Thank you for your comment! I tried on another PC and it started to compute IIS.So maybe the model is on the brink of infeasibility as you said.I'll check the guidelines to reset parameters pertain...
