You need to make the difference between the language semantics and a particular implementation. The user who writes a model in MathProg uses the solve statement to solve his model and obtain a solution; formally he knows nothing about lpx_read_model. Glpk api in this case is a metalevel. _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
