MATLAB API: Some inequality constraints as equality with slack variables(12.6)

  • 1.  MATLAB API: Some inequality constraints as equality with slack variables(12.6)

    When writing a MIP model with the CPLEX API in MATLAB (CPLEX 12.6) and exporting a .lp file, some inequality constraints are written as inequality constraints, and others are written as equality constraints with slack variables.

    Is there a way to control this?

    The constraints are still of course correct, but for reading and debugging an exported model I would rather have constraints written as I would expect to read them (inequalities).

     

    Thank you!

    That sounds rather strange. Could you give an example of such an inequality, how you specify it in matlab and how it appears in the LP file?

    Thanks for the reply. I will work on making a small example that exhibits the behavior and post it.
