NEOS Interfaces to OCTERACT

Sample Submissions


The Octeract Engine is a Deterministic Global Optimisation (DGO) solver which solves general mixed-integer nonlinear and linear problems to guaranteed global optimality. Acceptable input formats include AMPL, NL and GAMS formats, as well as LP and MPS formats for LP/MILPs. Details on Octeract can be found on the Octeract website.

Using the NEOS Server for OCTERACT/AMPL

The user must submit a model in AMPL format. Examples are provided in the examples section of the AMPL website.

The problem must be specified in a model file. A data file and commands files may also be provided. If the commands file is specified, it must contain the AMPL solve command; however, it must not contain the model or data commands. The model and data files are renamed internally by NEOS.

The commands file may include option settings for the solver. To specify solver options, add

  option octeract_options 'OPTIONS';
where OPTIONS is a list of one or more of the available solver options for AMPL.
