NEOS Interfaces to MOSEK

WWW Form & Sample Submissions


The NEOS Server offers MOSEK for the solution of optimization problems in AMPL format. MOSEK is an extremely efficient implementation of an interior point algorithm for the solution of linear and mixed integer programs and convex nonlinear programs. Highlights of the MOSEK optimizer are:
  • It employs the best interior-point technology.
  • Basis identification for linear problems.
  • A primal simplex optimizer is available for linear problems.

Using the NEOS Server for MOSEK

The user must submit a model in AMPL format. Examples of models in AMPL format can be found in the netlib collection.

The model is specified by a model file, and optionally, a data file and a commands file. If the command file is specified it must contain the AMPL solve command.

The commands file can contain any AMPL command or set options for MOSEK with, for example,

option mosek_options "outlev=2 MSK_DPAR_INTPNT_TOLPFEASNLO=1.0e-05";

Options include any of the parameters listed in The MOSEK optimization tools manual, see Printing directed to standard out is returned to the user with the output.
