## Overview

This repository is a small educational set of Python examples for solving linear programs with the simplex method. Each script is self-contained: its example constructs a model, calls its local solver, and reports results; the investment-risk example also plots risk versus profit. The solver implementation is repeated across all three files rather than shared as a package. The README points to a technical blog but documents no further runtime capabilities.

Main entry points: [`LP_math_model.py`](https://github.com/privateeye-zzy/simplex/blob/master/LP_math_model.py) (Risk model example), [`LP.py`](https://github.com/privateeye-zzy/simplex/blob/master/LP.py) (Basic LP example), [`LP_math_model2.py`](https://github.com/privateeye-zzy/simplex/blob/master/LP_math_model2.py) (Investment example)
