This skill orchestrates sequences of LP, MILP, or QP runs to trace non-dominated solutions across competing targets like budget versus coverage. It starts by constructing a payoff table from individual single-objective solves, which establishes scale ranges and bounds for normalization. Exploration uses either weighted-sum sweeps or the ε-constraint formulation. The weighted-sum approach runs quickly but catches only the convex hull, leaving gaps in discrete models. Shifting secondary goals into constraints and sweeping their bounds with the ε-constraint method captures the complete curve, including non-convex segments. For MILP models, cuOpt supports only linear constraints, and non-convex quadratic constraints fail on any path. In smooth LP and QP sweeps, constraint duals yield the exact tradeoff slope between objectives without extra compute. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill cuopt-multi-objective-exploration -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/cuopt-multi-objective-exploration/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cuopt-multi-objective-exploration/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill cuopt-multi-objective-exploration -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/cuopt-multi-objective-exploration/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill cuopt-multi-objective-exploration -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/cuopt-multi-objective-exploration/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install NVIDIA/skills cuopt-multi-objective-exploration ``` 2. **Manually: put the files in place** - File: `.github/skills/cuopt-multi-objective-exploration/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill cuopt-multi-objective-exploration -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/NVIDIA/skills --path skills/cuopt-multi-objective-exploration ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/cuopt-multi-objective-exploration/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill cuopt-multi-objective-exploration -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/cuopt-multi-objective-exploration/SKILL.md ## When to use it - trace the Pareto frontier across conflicting business metrics - generate payoff tables to establish bounds and scales across objectives - map non-convex tradeoff regions using the ε-constraint technique - extract marginal exchange rates between targets from constraint duals ## Example prompts - Map the Pareto frontier between inventory holding cost and stockout risk in cuOpt - Build a payoff table for these two competing objectives to find normalization scales - Sweep the budget limit as an epsilon-constraint to plot the cost-vs-service curve ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

Many real problems have several objectives that pull against each other — cost vs. service level, return vs. risk, makespan vs. overtime, distance vs. vehicle count. A single solve answers "what's optimal *for one particular weighting*," but it hides the tradeoff the user actually needs to see. This skill turns a sequence of single-objective cuOpt solves into a **Pareto frontier** — the set of solutions where you can't improve one objective without giving up another — and gives the discipline to read it. It adds no solver features; it orchestrates the LP / MILP / QP solves already covered by the formulation and API skills. ## When this applies Reach for this workflow when the problem has **two or more objectives with no agreed-upon weighting**, signalled by language like: - "balance X and Y", "trade off", "as cheap as possible *without* hurting service" - "minimize cost *and* maximize coverage", "I want options, not one answer" - any objective the user is willing to relax in exchange for another If there is a single clear objective (everything else is a hard constraint), this skill does not apply — formulate and solve once. ## Core idea — one solve is one point on a curve A single optimum encodes **one implicit weighting** of the objectives. Change the weighting and the optimum moves. The frontier is the curve traced by all the non-dominated optima. A solution **A dominates** B when A is at least as good on every objective and strictly better on one. Dominated solutions are never worth choosing. The **Pareto frontier** is exactly the non-dominated set; the user's job is to pick a point on it, and yours is to show them the whole curve plus where the tradeoff is sharpest. Do not collapse a multi-objective problem to a single weighted number and report its optimum as "the answer" — that silently makes the tradeoff decision *for* the user. Trace the frontier and let them choose. ``` END THIRD-PARTY FILE 649471b2797939ee The third-party file has ended.
