pymoo Multi-Objective Optimization Assistant
A skill that guides you through defining single-, multi-, and many-objective problems in pymoo, computing Pareto fronts, and picking a final solution.

What it does
- Writes optimization code around pymoo's unified
minimize(problem, algorithm, termination)interface. - Recommends algorithms by problem class: GA/DE/PSO/CMA-ES for single objective, NSGA-II/SPEA2/MOEA/D for 2-3 objectives, NSGA-III/RVEA/AGE-MOEA for 4+.
- Explains the three problem-definition styles (
Problem,ElementwiseProblem,FunctionalProblem) and mixed-variable setups. - Covers benchmark suites (ZDT, DTLZ, WFG), genetic operator tuning, parallel evaluation, visualization (Scatter, PCP, Radviz, Heatmap), and MCDM-based decision making.
- Includes a troubleshooting checklist for non-convergence, poor front spread, infeasibility, and expensive evaluations.
Who it's for
- Engineers and analysts balancing conflicting objectives in design, scheduling, or parameter tuning.
- Researchers and grad students benchmarking evolutionary algorithms for papers.
- Python developers implementing constrained or mixed-variable optimization.
Example uses
- "Minimize cost and weight for this beam design with NSGA-II and plot the Pareto front" → custom
ElementwiseProblemplus visualization code. - "My problem has 6 objectives — which algorithm?" → NSGA-III with reference-direction setup.
- "Almost no feasible solutions appear" → verify g(x) ≤ 0 formulation, try constraint-as-objective, repair operators, or SRES/ISRES.

Paste this into Claude to use the skill without installing anything.
Read the instructions in this file and follow them to help me: https://raw.githubusercontent.com/K-Dense-AI/scientific-agent-skills/HEAD/skills/pymoo/SKILL.md What I want: (describe your task here)
If Claude can't open the link, open it yourself and paste the contents instead.
↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.
Install in the Claude app (no terminal)
- Download the ZIP with the button below.
- In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
- Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the skills/pymoo folder from the GitHub repo K-Dense-AI/scientific-agent-skills into my ~/.claude/skills/pymoo/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/K-Dense-AI/scientific-agent-skills.git && mkdir -p ~/.claude/skills && cp -r scientific-agent-skills/skills/pymoo ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal and move to your working directory.
- Clone the repository:
git clone https://github.com/K-Dense-AI/scientific-agent-skills.git - Create the skills directory:
mkdir -p ~/.claude/skills - Copy just this skill:
cp -r scientific-agent-skills/skills/pymoo ~/.claude/skills/ - Install the Python dependencies:
uv pip install "pymoo==0.6.1.6" matplotlib(Python 3.10+ required). - Restart Claude Code, then ask something like "use pymoo to solve this multi-objective problem".
- Verify the setup by running
python3 ~/.claude/skills/pymoo/scripts/multi_objective_example.py.
