MindtPy Solver system requirements
MindtPy Solver is a powerful mixed integer nonlinear programming optimization tool that can be run on any hardware capable of running Python. However, to run MindtPy, you need Python 3.7 or higher installed on your system. Pyomo, “Requirement, https://pyomo.readthedocs.io/en/stable/installation.html#:~:text=CPython%3A%203.7%2C%203.8,PyPy%3A%203″
The system requirements may vary depending on the size and complexity of the problems you plan to solve. While there is no specific minimum requirement, we recommend the following specifications:
- Operating System: Windows, Mac, or Linux
- Processor: 2 GHz dual-core processor or higher
- RAM: 4 GB or more
- Storage: 15 GB or more
- Internet Connectivity: Optional
By meeting these recommended specifications, you can run MindtPy Solver efficiently.
Download and install Python
Python is a popular object-oriented programming language for various tasks, including web development, data analysis, and artificial intelligence. To run MindtPy, you must download and set up a proper Python environment on your device.Python, “What is Python, https://www.python.org/doc/essays/blurb/#:~:text=Python%20is%20an,of%20program%20maintenance.”
In this section, we’ll provide step-by-step instructions on how to download and install Python on your Windows computer.
Step 1. Check if Python is already installed on your computer
The first step is to check if Python is installed on your computer. To do this, press the Start button and type cmd to open Command Prompt.
In the command prompt, type python –version and press Enter. If nothing appears like image given below, Python is not installed on your computer.
Now, we’ll learn how to download and install Python.
Step 2. Download Python
Step 3. Install Python
After the download, go to your downloads folder and double-click on the executable file to run it.
Now, you’ll get an Install Python screen. Click the Customize installation option.
Following that, you’ll see an Optional Features screen. Ensure the pip (Python package manager)option is checked, and click Next.
On the next screen, make sure you check Add Python to environment variables and Precompile standard library options. After that, click Install to begin the installation process.
You can also chnage the installation location of Python if you wan to.
After the installation, you’ll see a Setup was successful screen.
Step 4. Check if Python was installed successfully
To check if Python was installed successfully, open the command prompt and type python –version, and press Enter as in Step 1.
If Python was installed successfully, you should see the version number of the Python-like image below.
That’s it! You’ve successfully downloaded and installed Python on your Windows computer. In the next step, we’ll install Pyomo and set up environments for MindtPy.
Downloading Pyomo and setting environments
Pyomo is a Python-based open-source software capable of analyzing optimization models.
In this section, we’ll provide step-by-step instructions on downloading Pyomo and setting up the necessary environments.
Step 1. Download Pyomo
To download Pyomo, open the Command Prompt on your computer and type pip install pyomo and press Enter.
This will download and install Pyomo on your computer. You’ll get a successful install message after completion.
Step 2. Download and set up Ipopt (Interior Point Optimizer)
Ipopt is an open-source optimization software for non-linear programming problems (NLP solver).
For this example, we’ll download the 64-bit version for Windows.
After downloading, extract the folder to your desired location on your computer. In this example, we’ll extract it to the New Volume (C:) drive.
Step 3. Setting up theIpopt environment
To set up the environment for Ipopt, open the Ipopt folder and the bin folder. Copy the folder location by clicking the address bar on the top.
Next, you need to open the Environments on your computer. The process of accessing environments varies depending on your Operating System.
For Windows, press the Start button and type environment. From the results, open the Edit the system environment variables option. You can also access this menu from the Control Panel or System Properties of your computer.
Click on the Environment Variables button.
In the Environment Variables window, under User variables, double-click on the Path option.
Click on the New option, and an insertion point will appear.
Now paste the Ipopt bin folder location that you copied earlier. Click OK to save your changes.
After completing these steps, you have downloaded and set up the Ipopt environment.
Step 4. Download and set up GLPK (GNU Linear Programming Kit)
GLPK is a free software package that solves large-scale linear programming (LP), mixed integer programming (MIP solver), and other related problems.
After downloading, extract the folder to your desired location on your computer. In this example, we’ll again extract it to the New Volume (C:) drive.
Step 5. Setting up the GLPK environment
To set up the environment for GLPK, open the GLPK folder followed by w64 folder. Copy the folder location by clicking the address bar on the top.
Next, you need to open the Environments on your computer. Follow the same methods as mentioned above to access the Environment Variables.
In the Environment Variables window, under User variables, double-click on the Path option like in Step 3 of Ipopt. Click New and paste the GLPK w64 folder location and click OK.
Running the MindtPy Solver code
The MindtPy Solver is a toolbox in Pyomo to solve mathematical optimization solver used to solve Mixed-Integer Nonlinear Programs (MINLP). Once you have installed and set up the environments, you can start running your code.
These approaches include:
- Outer approximation method (OA)
- Global outer approximation (GOA)
- Regularized outer approximation (ROA)
- LP/NLP based branch-and-bound (LP/NLP)
- Global LP/NLP based branch-and-bound (GLP/NLP)
- Regularized LP/NLP based branch-and-bound (RLP/NLP)
- Feasibility pump (FP)
In this section, we’ll test a code given in the official documentation of the solver.
Step 1. Open Command Prompt and run Python. Type python on CLI (Command Line Interface) and press Enter.
Step 2. Paste the code given below and press Enter.
from pyomo.environ import * model = ConcreteModel() model.x = Var(bounds=(1.0,10.0),initialize=5.0) model.y = Var(within=Binary) model.c1 = Constraint(expr=(model.x-4.0)**2 - model.x <= 50.0*(1-model.y)) model.c2 = Constraint(expr=model.x*log(model.x)+5.0 <= 50.0*(model.y)) model.objective = Objective(expr=model.x, sense=minimize) SolverFactory('mindtpy').solve(model, mip_solver='glpk', nlp_solver='ipopt') # doctest: +SKIP
If your installation was successful, you’ll see a message without errors, like the image given below.
Run any of the objective function given below:
For this example, we’ll type model.objective.display() and press Enter. Your output must look like this.
If you run model.display(), you’ll get the output as in the image below.
