Gurobi Docs Navigation

Overview

Navigate the Gurobi Optimizer docs at https://docs.gurobi.com/projects/optimizer/en/ to answer questions accurately. The site has three sections: Concepts (foundational), Features (advanced capabilities), Reference (API/attributes/parameters).

Default version: current (= Gurobi 13.0). For version-specific queries, replace current with the version number (e.g., 11.0, 12.0).

Default language: Python (gurobipy). Switch to user's language if their code shows otherwise.

Navigation Decision Tree

What is the question about?
│
├── "What is X?" / "How does X work?" / modeling fundamentals
│   → CONCEPTS: https://docs.gurobi.com/projects/optimizer/en/current/concepts/
│
├── Named feature: callbacks, infeasibility, solution pool,
│   multiple objectives, nonlinear, tuning, distributed, cloud
│   → FEATURES: https://docs.gurobi.com/projects/optimizer/en/current/features/
│
├── A specific API method, class, or function
│   (e.g., addConstr, Model, addMVar, setParam)
│   → REFERENCE/Python: https://docs.gurobi.com/projects/optimizer/en/current/reference/python.html
│   (or other language — see language table below)
│
├── A Gurobi attribute (e.g., ObjVal, Status, X, Pi, RC, MIPGap)
│   → REFERENCE/Attributes: https://docs.gurobi.com/projects/optimizer/en/current/reference/attributes.html
│
├── A Gurobi parameter (e.g., TimeLimit, MIPGap, Threads, Presolve)
│   → REFERENCE/Parameters: https://docs.gurobi.com/projects/optimizer/en/current/reference/parameters.html
│
├── Numeric/status codes (e.g., GRB.OPTIMAL, GRB.Status.*)
│   → REFERENCE/Numeric Codes: https://docs.gurobi.com/projects/optimizer/en/current/reference/numericcodes.html
│
└── Version-specific question ("in Gurobi 11", "what changed in 12")
    → Swap `current` for version: /en/11.0/, /en/12.0/, /en/13.0/

How to Navigate

1. Pick the URL using the decision tree above.
2. WebFetch the page directly — don't use the search box.
3. If the page 404s, check references/url-map.md for the exact URL, then try the parent section.
4. For API method details, go to the class page (e.g., reference/python/model.html for Model.addConstr).

Attributes vs Parameters — common confusion:

• Attribute: value read/written on a model/var/constraint object after adding it. Example: var.X (solution value), model.ObjVal, constr.Pi. Read via obj.getAttr() or obj.AttrName.
• Parameter: solver setting configured before solving. Example: model.setParam("TimeLimit", 60). Lives in reference/parameters.html.

Version Handling

• Omit version from query → use current
• "Gurobi 11" → /en/11.0/
• "Gurobi 12" → /en/12.0/
• "Gurobi 13" → /en/13.0/ (same as current)
• "latest" → current
