I see three reasons you need to save the basis in a file: a) you would like to run an LP which has been solved just to reproduce results (for example, to debug printing report in MathProg model). In this case you can use the options '-w filename' / '-r filename'; b) you would like to process the file with another application. Again, you can use the options -w/-r; c) you would like to solve a similar LP using the basis saved as a starting point. Currently it is impossible, because glpk has no feature to construct a similar basis. However, if that similar LP has *exactly* the same set of rows and columns as the original one (for example, only some constraint/objective coefficients were changed), you can use the options -w/-r. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
