OptiGen 0.1.1

OptiGen is a tool for automatically generating optimization projects from natural language.

OptiGen

An AI-powered optimization modeling assistant built on LangGraph.

OptiGen guides users through formulating optimization problems—from defining objectives and constraints to generating and validating Python solvers.

Features

• Guided Problem Formulation: Step-by-step process to define objectives, constraints, and data schemas
• Quick Start Mode: Build initial models using popular assumptions for common problem types (VRP, scheduling, inventory)
• Solver Generation: Automatically generate Python optimization scripts
• Validation: Test solvers against example data to verify correctness

Getting Started

1. Copy .env.example to .env and add your API keys
2. Start the development server:

   make start
   

   This will start the LangGraph dev server and open the browser automatically.

Alternatively, you can open the project in LangGraph Studio.
