FAQs

Solvers purchased through AMPL are available at a lower cost because they are designed to work exclusively with AMPL. While they may not include standalone vendor features (e.g., gurobipy for Gurobi), AMPL provides powerful integrations like amplpy to ensure flexibility.

Yes. Our solvers include AMPL’s MP interface, which enables intelligent problem reformulation, often converting nonlinear models to linear for faster solving. These optimizations can significantly reduce solve times and improve efficiency.

Yes, AMPL supports solver flexibility. If your problem evolves and requires a different solver, our team can help you assess and transition to the best solver for your needs.

We offer solver selection consulting to help you choose the best solver based on your problem type, performance needs, and budget. We also provide benchmarking and tuning services to ensure you’re getting the most out of your solver.

AMPL-licensed solvers are optimized for use within AMPL and may not support standalone vendor-specific APIs like gurobipy. However, AMPL provides powerful integrations such as amplpy for Python users.

AMPL provides technical support for solver integration and setup. For advanced solver tuning and performance optimization, we offer custom consulting services to help you get the best results.
