Hello Andrew C:\>glpsol.exe --dfs --nopresol -m s.mod
gave the following output GLPSOL: GLPK LP/MIP Solver 4.39 Reading model section from s.mod... 132 lines were read Generating start... Generating end... Generating onemove... Generating delta... Model has been successfully generated ipp_basic_tech: 66 row(s) and 66 column(s) removed ipp_reduce_bnds: 1 pass(es) made, 0 bound(s) reduced ipp_basic_tech: 0 row(s) and 0 column(s) removed ipp_reduce_coef: 1 pass(es) made, 0 coefficient(s) reduced glp_intopt: presolved MIP has 1054 rows, 3346 columns, 11404 non-zeros glp_intopt: 2356 integer columns, all of which are binary Scaling... The output was just the same if --presol is specified. I would have expected no column to be removed with --nopresol.
