dyca SKILL.md skillA
dyca 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/dyca@git:20260908.f40b41bPins git:20260908.f40b41b in mdr.lock. Pin the fingerprint instead.

DyCA (Dynamic Clustering Algorithm) method skill. USE WHEN the user explicitly requests DyCA / dynamic clustering adaptive evolution, or wants instance-aware search that clusters problem instances and allocates specialized algorithm pools via dynamic reclustering and resource allocation.
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
# DyCA (Dynamic Clustering Adaptive) Skill > **Reference**: LLM4AD_Next instance-aware multi-pool evolution model (DyCA, Dynamic Clustering Algorithm). ## 1. Method Essence DyCA is an **instance-aware** search method. Instead of treating all problem instances uniformly, it dynamically partitions the training instances into **clusters** and maintains **heterogeneous algorithm pools** specialized to those clusters. The search then allocates LLM effort across pools based on observed difficulty and cluster stability. Three heterogeneous pools: | Pool | Role | |---|---| | **Generalist pool** | Global best algorithms that perform well across all clusters | | **Specialist pools** | Per-cluster optimized algorithms (one pool per cluster) | | **Complementary pool** | Cross-cluster diversity algorithms that complement others | Core mechanisms: - **Per-instance evaluation** and cluster-specific fitness - **Dynamic reclustering** based on Adjusted Rand Index (ARI) stability - **SOS (Save Our Specialist)** inter-cluster collaboration to escape local optima - **Macro (ARI-based) and micro (gap-based) resource allocation** ## 2. Recommended Parameters …

How to install
mdr add optima-cityu/llm4ad_next/dyca@sha256:df465c0878ee0bd1The line at the top of this page pins the label git:20260908.f40b41b, 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.
