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.
The user must submit a model in AMPL
format. Examples are provided in
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';
