RE: [AMPL 6830] About reading variable names of an 'Adjusted problem' when presolve is done

[Robert Fourer]

The command

 

   print {j in 1.._snvars}: _svarname[j];

 

gives a list of the names of the variables that are sent to the solver, after the presolve phase.  Hence this list corresponds to the adjusted problem described in the "show_stats 1" statistics.

Subject: [AMPL 6830] About reading variable names of an 'Adjusted problem' when presolve is done

 

Hello,
AMPL option 'show_stats 1' outputs statistics to reflect an adjusted problem. Is there any way to list all variable names in the adjusted problem?

Thanks!
