LINGO was unable to find a solution that simultaneously satisfies all the constraints. Check the model抯 consistency. Try dropping constraints until the problem goes away to get an idea of where the trouble may lie. Also, check the solution report. Constraints contributing to the infeasibility will have a nonzero dual price.
If you'e solved a model and brought another model window to the front, LINGO prints this message to remind you that the solution you'e asked for may not belong to the frontmost model window. LINGO also prints this message whenever you attempt to examine a nonoptimal solution; for instance, when you'e interrupted the solver, or when LINGO couldnt any find a feasible answer. In the latter case, correct any errors in the model and re-solve.
No feasible solution found.
