# Basic LP Example using cuopt_cli
#
# This example demonstrates how to solve a simple LP problem using cuopt_cli.
# cuopt_cli is a standalone command-line tool that solves LP/MILP problems
# from MPS files without requiring a server.
#
# Requirements:
#   - cuopt_cli installed and available in PATH
#

# Create a sample MPS file
