    Excuse me,

    I have tested a MILP problem in cmd both with lp and mps file. the lp file can be successfully solved while the mps file failed. I also tries to solve the mps problem in lpsolve IDE, it seems it is feasible with the same results obtained through cmd. Does anyone know why this would happen? I tried to use conflict refiner. But it doesn't find any conflict. SO what is the real reason resulting in the infeasibility for the mps problem?

    Thanks in advance.

    this problem has been solved that is because the mps format generated by lpsolve is not compatible with cplex.
