AMPL Optimization

The page lists the best solver options for a variety of problem areas. Other solvers may be equally good or better but we recommend to start an evaluation with the options below.

• Linear programming (sparse) - AMPL /MINOS - MINOS
   
• Linear programming (dense) - AMPL /MINOS - QPOPT
   
• Quadratic programming (sparse) - AMPL /SNOPT - SQOPT
   
• Quadratic programming (dense) - AMPL /SNOPT - QPOPT
   
• Nonlinear programming (sparse) - AMPL /SNOPT - SNOPT
   
• Nonlinear programming (dense) - AMPL /NPSOL - NPSOL
   
• Linear Least Squares (dense) - AMPL /NPSOL - LSSOL
   
• Nonlinear Least Squares (sparse) - AMPL /SNOPT - SNOPT
   
• Nonlinear Least Squares (dense) - AMPL /NPSOL - NLSSOL
   
• Box-bounded (unconstrained) global optimization - AMPL /BASE - glbDirect
   
• Mixed-Integer constrained global optimization - AMPL /BASE - glcDirect
