Introduction

This is a final project that I did as a student for course ORI 391.Q nonlinear programming that I took in Spring 2024 with Professor Bollapragada. The assignment involved implementing several different optimization algorithms on several different problems and comparing success minimization metrics and convergence properties.

Instructions to Run Code

To run this code, first setup and active a Python virtual environment. All the other instructions in this README will assume that such an environment has been setup and activated.

virtualenv setup

cd nonlinear-programming
rm -rf venv
# This is assuming you are using Homebrew. If you are using some other environment, adjust this command accordingly.
/opt/homebrew/opt/[email protected]/bin/python3.12 -m venv venv
source ./venv/bin/activate
pip3 install --upgrade pip setuptools
pip3 install -r requirements.txt

Run code lint and unit tests

Run flake8 lint code verification and pytest unit tests:

make flake8
make test

See the function that matches the final project assignment

The final project assignment specifies a function of the form:

[x, f] = optSolver-TeamName(problem,method,options)

That function exists in final_project.py with some example usage.

Generate tabular results in .html format

# optionally remove any old results.
rm -rf generated/

python generate_html_benchmarks.py

# open .html files in generated/ directory.

Generate line search parameter comparison results in .csv format

# optionally remove any old results.
rm -rf generated/

python evaluate_line_search_parameters.py
