CPLEX Error 1707: Infeasibility Finder requires a basic solution.

[Lukas]

Dear all,
could you please help me,  where to find the problem with infeasibility in LST file? The infeasibility is caused by the scenario file, that I attach too. Thank you!

The listing file only gives the following information about the problem:

CPLEX Error  1707: Infeasibility Finder requires a basic solution.

*** Out of memory.

Indeed, this indicates that your model is infeasible. If you see that happening only by including the scenario you attached, I think it should be caused by one of the UC constraints active in that file. As far as I can see, there are 13 of them, and so it shouldn't be too tedious to analyse which one(s) are infeasible.  Some options:

  1) Analyze the constraints by manual inspection
  2) Use binary search to identify the infeasible constraints (four test runs would be needed for the 13 candidates)
  3) Activate the VEDA dummies for UCs and see which constraint gives you dummies
  4) Use the default LP method instead of barrier and let the Cplex infeasibility finder to find the infeasibilities for you

Thank you Antti, manual inspection worked.
