What it does
Diverse Island Ga is an agent skill from Optima-CityU/LLM4AD_Next. Diverse Island Genetic Algorithm skill. USE WHEN the user explicitly requests Diverse Island GA / diversity-oriented island GA, or wants specialized island roles with adaptive migration and novelty preservation instead of a uniform island GA.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `params.yaml`).
The repository describes itself as: A next-generation automatic algorithm design platform, making automated algorithm design more accessible and easier to use. The licence is BSD-3-Clause.
When your agent uses it
- The user explicitly requests Diverse Island GA / diversity-oriented island GA
- Wants specialized island roles with adaptive migration and novelty preservation instead of a uniform island GA
Example prompts
- “/diverse-island-ga”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit e3d3f7b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Diverse Island Ga loads about 855 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 343 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Diverse Island GA Skill
Reference: LLM4AD_Next specialized island model. Extends IslandGA with specialized island roles (a continuous exploitation↔exploration spectrum), adaptive stagnation-aware migration, and novelty preservation.
1. Method Essence
Diverse IslandGA builds on the classic island model but removes the assumption that all islands are identical. Instead, it assigns each island a continuous strategy position along the exploration↔exploitation spectrum, and coordinates them through adaptive migration that fires only when an island stagnates. This keeps the population diverse and avoids the premature spread of a local optimum.
Core mechanisms:
| Concept | Role |
|---|---|
| Island strategy spectrum | island_strategy_strength controls how much islands differ (experience-reuse → novelty exploration) |
| Adaptive migration | adaptive_migration receives migrants only after an island stagnates |
| Stagnation threshold | migration_stagnation_threshold consecutive non-improving generations before migration is allowed |
| Novelty survivor | novelty_survivor_ratio reserves non-elite survivor slots for code-dissimilar individuals |
| Exploration restart | exploration_restart_ratio share of candidates built from scratch on the most exploratory island |
| Short-run guard | short_task_max_migrations caps migration events on short runs |
2. Recommended Parameters
See params.yaml in this directory for the recommended parameter configuration.
Note: This variant ships with a smaller out-of-box workload (max_generations=10, island_population_size=5) than the plain IslandGA, so it is safe to run without heavy tuning.
What Happens During Evolution
- Initialize
num_islandsislands, each at a distinct point on the strategy spectrum - Each island evolves with its own exploration/exploitation bias and memory policy
- Every generation, elites are reevaluated at higher fidelity (
elite_reevaluation_count) - Migration is adaptive: an island may receive migrants only after
migration_stagnation_thresholdnon-improving generations - Novel survivors (low code similarity) are retained to preserve diversity
- On short runs, migration is capped by
short_task_max_migrations
Common Pitfalls
- Uniform islands (strength too low) → little diversity benefit; raise
island_strategy_strength - Migration too aggressive → premature convergence; rely on adaptive stagnation gating
- Exploration island flooding → tune
exploration_restart_ratioand novelty ratio - Short runs over-migrating → keep
short_task_max_migrationslow (default 1)
4. Acceptance Criteria
- Islands occupy distinct points on the exploration↔exploitation spectrum
- Migration triggers only after stagnation (adaptive, not periodic-only)
- Novelty survivors maintain inter-island diversity
- Short runs respect the migration cap
- Final best beats a uniform IslandGA baseline on the same problem
