Hi there,

  We have been using IIS for finding the conflicts that are present in LP model. We set IISInd flag to 1 to get limilted amount of conflicts. Currently, we have moved to CPLEX11. IIS is deprecated in CPLEX10. However, we are still able to use IIS in CPLEX11. Since IISInd flag is removed from CPLEX11, we are unable to set parameter to 1 to indicate that we need limited number of conflicts. We tried using conflict refiner in place of IIS as suggested by CPLEX manual. It seems like the number of conflicts retuned by refineconflict is similar to getting conflicts from IIS with IISInd parameter set to 0 (ie it returns more number of conflicts).

Can you please suggest a solution? Is it possible to still use IIS in CPLEX11 and control it to give only limited set of conflicts?

If not, is there a way in conflict refiner to make sure we get limited set of conflicts? (to replicate IIS with IISInd flag set to 1)

Thank you

apparently you posted your question under "constraint programming - general". Probably you could get the attention of the right people if you posted this question in the ILOG CPLEX section. constraint programming is something entirely different from what CPLEX is...besides, your question is about the product...

Thank you

I have moved the discussion to ILOG-CPLEX.
