TOMNET /SOL

The TOMNET /SOL toolbox efficiently integrates the well-known solvers developed by the Stanford
Systems Optimization Laboratory (SOL) with .NET and TOMNET. The toolbox includes

• The sparse general nonlinear solver SNOPT 7.1-1,
   
• The sparse positive convex quadratic solver SQOPT 7.1-1,
   
• The dense general constrained nonlinear solver NPSOL 5.0,
   
• The sparse constrained linear least squares solver LSQR,
   
• The dense constrained linear least squares solver LSSOL 1.05 and
   
• The dense constrained nonlinear least squares solver NLSSOL, based on NPSOL.
   
• Read more about the above mentioned SOL solvers, as well as the TOMNET /MINOS solvers MINOS and QPOPT, at the SBSI-SOL Home page.
   
• TOMNET /SOL includes all .NET code and solvers that are part of TOMNET /MINOS, see the description of TOMNET /MINOS.
   
• For a general description of the TOMNET features, see the TOMNET FEATURES.
   

  Main features

• The codes are implemented to efficiently handle .NET sparse arrays.
   
• Using the TOMNET graphical interface (GUI) all solver parameters and features are selectable.
   
• It is easy to use warm starts for the SOL solvers, and further speed up sequences of optimization solutions.
   
• NPSOL has been used intensively in control applications because of its speed and robustness.
   
• All SOL solvers may be used as sub problem solvers for other TOMNET solvers.
   
• The SPECS file input format, that is used by all SOL solvers when running non-.NET, is also possible to use.
   
• NPSOL and SNOPT may estimate derivatives internally, faster than using the TOMNET method.

Requirements

• Windows 32-bit .NET 2.0+
