I have a model constructed with OPL language.
I have some variables indexed in a set with double indices. X_ij (where i,j \in Subset)
I have exported this model to an lp file, to work with Cplex with Matlab connector.
This lp file names the variables with one index.
I would like to use a MipStart. So I need to identify the name of the variables with my original definition.
- Is there a way I can maintain the original names?
- Or how can I identify the names of the variables in the lp file with my original variables?
