Hello Julian !I did a mistake on implementing the OBJSENSE for freemps format and fixed it now the binaries are available here https://github.com/mingodad/GLPK/actions/runs/2324392030 and here is the generated freemps:
==== * Problem: simple_max * Class: LP * Rows: 3 * Columns: 2 * Non-zeros: 6 * Format: Free MPS * NAME simple_max OBJSENSE MAX ROWS L Constraint1 L Constraint2 N Objective COLUMNS x Constraint1 1 Constraint2 3 x Objective 1 y Constraint1 2 Constraint2 1 y Objective 1 RHS RHS1 Constraint1 15 Constraint2 20 ENDATA ==== Cheers !

Hello Julian !Meanwhile I implemented read/write OBJSENSE for freemps format on my fork of GLPK with several extensions and here https://github.com/mingodad/GLPK/actions/runs/2324178367 you can find the binaries built with github actions to try.With your proposed example the solution is the same on both, and here is the generated freemps:==== * Problem: simple_max * Class: LP * Rows: 3 * Columns: 2 * Non-zeros: 6 * Format: Free MPS * NAME simple_max OBJSENSE MAX ROWS L Constraint1 L Constraint2 N Objective COLUMNS x Constraint1 1 Constraint2 3 x Objective 1 y Constraint1 2 Constraint2 1 y Objective 1 RHS RHS1 Constraint1 15 Constraint2 20 ENDATA ==== Cheers !
