Gurobi MIP Bounds Tracking with Callback

This repository provides a Gurobi Code for tracking upper and lower bounds during Mixed-Integer Programming (MIP) optimization. Using Gurobi's callback, it collects bound information and plots their evolution in real-time.

📊 Features

• ✅ Tracks upper and lower bounds for any MIP problem.
• ✅ Uses Gurobi's callback function to collect bound updates during optimization.
• ✅ Visualizes the bound progression with Matplotlib.

This is useful for:

• Benchmarking solution convergence over time.
• Understanding how Gurobi improves bounds during solving.
• Comparing different MIP models or parameters.

📚 Reference

The callback mechanism for collecting bounds is inspired by code found in the Gurobi Community Forum:
