description

Use when the user asks anything about Gurobi or gurobipy — API methods (addConstr, addVar, addMVar, optimize, setParam, getAttr), parameters (TimeLimit, MIPGap, Threads, Presolve, PoolSolutions), attributes (ObjVal, Status, X, Pi, RC, ObjBound), solver features (callbacks, IIS/infeasibility, solution pool, multiple objectives, nonlinear), status/error codes, or version-specific changes (Gurobi 11, 12, 13). Always use this skill instead of answering from memory — Gurobi API details change between versions and require doc verification.

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.

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
