- How do I instruct Gurobi to produce a log file?
- How do I suppress all console output from Gurobi?
- How do I send the log to a file without also printing to the console?
- What does "Presolve: All rows and columns removed" mean?
Multi-Objective Optimization
- How do I set termination criteria in multi-objective environments?
- How do I return to single-objective mode from multi-objective optimization?
- How do I query best bound and best objective values in multi-objective optimization?
- What does Gurobi return when the first pass in a hierarchical multi-objective optimization terminates with no solution?
Infeasibility
- How do I use 'compute IIS' to find a subset of constraints that are causing model infeasibility?
- How do I change variable and/or constraint bounds to make an infeasible model feasible using feasRelax?
