How to set up Octeract Engine for Windows

Step 1: Install the Engine

After you save the Engine and licence files to a chosen location on your PC, you can install the Engine. You’ll need to first unzip the folder and then, double click on the installer. Follow the on-screen instructions. Installation complete.

Step 2: Run a Command

To get started, navigate to the nl folder in the examples folder and run the command in the first snippet. The Engine reads .nl, .lp and .mps directly. It also reads .py, .mod and .gms through Pyomo, AMPL and GAMS respectively.

Objective value at global solution: -1.700e+01

Step 3: Download Python 3.7

If you would like to use the Python API, Python needs to be installed on your system. Download and install Python 3.7 for your OS.

Step 4: Create a Model

To set up a new model, use the Python syntax:
m = Model() then set an objective, constraints, and variable bounds. Use the syntax print(m) to view the model before solving the problem.


from octeract import *

m = Model()
m.set_objective("x1-x2")
m.add_constraint("x1 - 6*x3 - 16*x4 - 10*x5 = 0")
m.set_variable_bounds("x1", 0, 100)
m.set_variable_bounds("x2", 0, 100)


print(m)

m.global_solve()

tar -zxvf OcteractEngine-1.10.1-Linux.tar.gz

Step 1: Install the Engine

After you save the Engine and licence files, you can install the Engine. You’ll need to untar the tarball (octeract.tgz file) to a chosen location on your PC. To do this, run the command, found in the snippet on the left, in a shell session. Then, add the bin folder to PATH and the lib folder to PYTHONPATH.
