moead SKILL.md skillA
moead from optima-cityu/llm4ad_next is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add optima-cityu/llm4ad_next/moead@git:20260825.2005c66Pins git:20260825.2005c66 in mdr.lock. Pin the fingerprint instead.

MOEA/D (Multi-objective Evolutionary Algorithm based on Decomposition) method skill. USE WHEN the user explicitly requests MOEA/D / Decomposition-based multi-objective evolution, or wants weight-vector decomposition with neighborhood collaboration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MOEA/D Skill > **Paper**: Zhang & Li, "MOEA/D: A Multiobjective Evolutionary Algorithm Based on Decomposition", IEEE TEC 2007. ## 1. Method Essence MOEA/D **decomposes** a multi-objective problem into N single-objective sub-problems: each sub-problem is defined by a weight vector + aggregation function (weighted sum / Tchebycheff), and the entire population = a set of uniformly distributed weight vectors. Core mechanisms: - **Sub-problem division**: Each weight vector corresponds to a direction on the front; the population collectively covers the entire front - **Neighborhood collaboration**: Each sub-problem exchanges information only with its T nearest weight vectors (neighbors) — crossover/mutation occurs mainly between neighboring sub-problems, replacing global pairing - **Aggregation function**: Tchebycheff `max_i w_i |f_i - z_i|` (z is reference point) is effective for non-convex fronts and is commonly used - **Update rule**: If a new individual improves the aggregation value for its sub-problem, it replaces that sub-problem and its neighbors' solutions ## 2. Recommended Parameters See `params.yaml` in this directory for the recommended parameter configuration. …

How to install
mdr add optima-cityu/llm4ad_next/moead@sha256:1cd6fedcd62e5fc0The line at the top of this page pins the label git:20260825.2005c66, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
