-1

I turned off the presolve because i need to get a result but when the result is infesiable and i try to read the result all the result that the program read are 0.

Someone knows how to read it??

  • of what possible value is an infeasible result? `pyomo` variables hold the last value when the solver quits, so if you must, inspect the variables... – AirSquid May 21 '21 at 17:30
  • when i get this result: Dual simplex - Infeasible: Objective = 2.9016000002e+04 Solution time = 0.30 sec. Iterations = 256 (0) Infeasible variable = slack c_e_x19140_ Deterministic time = 245.10 ticks (825.27 ticks/sec) I get the result of the last iteration or if it is the first i dont get any result – Leonel Henríquez May 21 '21 at 21:14

What you can do is export into a mps file from pyomo and then import in docplex and then tun the relaxation CPLEX tool:

See Infeasible Solution Handling with Python cvxpy and Python_MIP() (CBC solver)
