The name of the file to which the model is written. The extension of the filename determines the format in which to write the model file.
Remarks
The file format is determined by the extension of the filename. The following extensions are recognized on most platforms:
.sav
.mps
.Lp
.sav.Gz (if gzip is properly installed)
.mps.Gz (if gzip is properly installed)
.Lp.Gz (if gzip is properly installed)
.Bz2 (if bzip2 is properly installed)
Microsoft Windows does not support writing gzipped files. If no name has been assigned to a variable or range (that is, getName returns null for that variable or range), Cplex uses a default name when writing the model (or in the optimization log). Default names are of the form IloXj for variables and IloCi, where i and j are internal indices of Cplex.
