Expérimenter avec l'évolution synthétique dirigée
Quand la théorie rencontre la réalité et que le code commence à évoluer Inspired by thinking about extensions to mostlylucid.mockllmapi and material for the (never to be released but I like to think about it 😜) sci-fi novel "Michael" about emergent AI
**Remarque:**Remarque:
C'est aussi très expérimental, un peu fou, et certainement "vibe-coded". Vous avez été prévenu.
De la théorie à la pratique :
En fait, je l'ai construit.
Après six parties de la théorie sur l'intelligence émergente, les systèmes multi-agents, le consensus mondial et la cognition à l'échelle planétaire, j'ai eu une réalisation:
J'étais en train de tergiverser.**Il est facile de spéculer sur les guildes synthétiques et l'intelligence en évolution.**C'est plus dur de le construire.
Alors j'ai arrêté de parler et j'ai commencé à coder.
Ce qui a émergé, c'est quelque chose que j'appelleEvolution synthétique dirigée (DSE)—un workflow auto-assemblant et auto-optimisant utilisant un système dynamique multi-niveaux et multi-agents alimenté par LLM.
Ou quelque chose ! (Regarde, j'invente ça au fur et à mesure.)Le pas de l'ascenseur: Et si au lieu de générer du code une fois et en espérant qu'il fonctionne, nous avons créé un système où le codeévolue en permanence
par la planification, l'exécution, l'évaluation et la mutation?
Et si nous pouvions apprendre à un système à apprendre de ses erreurs, à réutiliser des modèles réussis et à devenir plus intelligents au fil du temps?Alerte de spoiler :. En fait, ça marche.*Et c'est bizarre.*Et fascinant.
Plongons dedans.
You: "Write me a function that does X"
LLM: "Here's some code! [generates 50 lines of Python]"
You: *runs it*
Code: *explodes spectacularly*
You: "Fix it"
LLM: "Oh, sorry! Here's a new version!"
You: *runs it*
Code: *different explosion*
AGAIN: C'est une EXPERIMENT ce n'est pas si stable et pas du tout rapide.
Mais ça fait ce qu'il dit sur le bout,
C'est vrai.Tout de suite.
ne font pas encore toutes ces opérations.
Le problème dont nous ne parlons pas
Voici comment fonctionne aujourd'hui la génération de code basée sur LLM :
Les questions sont fondamentales :
Génération d'un seul coup
- Pas d'itération, pas de raffinement, pas de seconde chance
Pas de mémoire
Pas de retour d'information sur la qualité

Approche traditionnelle (prononcé à l'hallucination) :
# Traditional similarity: might give false positives
Task 1: "generate fibonacci sequence"
Task 2: "generate fibonacci backwards"
Similarity: 77% ← High, but these need DIFFERENT code!
# Semantic classification
Triage LLM analyzes both tasks:
SAME → Reuse as-is (just typos/wording differences)
RELATED → Use as template, modify (same domain, different variation)
DIFFERENT → Generate from scratch (completely different problem)
Result: "RELATED - same core algorithm, reversed output"
Action: Load fibonacci code as template, modify to reverse

Évolution de l'adversaire
Méta-évolution
Système développant ses propres stratégies d'évolutionApprentissage collaboratif- Plusieurs instances DSE partageant des découvertes
Enseignements tirésAprès avoir construit ce truc, voici ce qui m'a surpris :
**1. Le Conseil de l'Europe a adopté une résolution du Conseil de l'Europe sur la situation des droits de l'homme dans le monde.**Questions de spécialisation
**L'utilisation de différents modèles pour différentes tâches (surveillant vs générateur vs évaluateur) n'était pas seulement agréable – c'était essentiel.**Essayer d'utiliser un modèle pour tout ce qui a produit des résultats nettement pires.
**2. Le Président. — L'ordre du jour appelle le rapport (doc.**La mémoire, c'est tout
La mémoire RAG n'est pas une fonctionnalité, c'est LA fonctionnalité.
Sans ça, tu ne fais que générer du code en boucle.Avec elle, le système apprend et s'améliore.
4. Le Président. — L'ordre du jour appelle le rapport (doc.
L'évolution fonctionne en faitHonnêtement, je ne m'attendais pas à ce que l'auto-évolution produise un meilleur code que la génération initiale.
Toujours.
**C'est sauvage.**5.
Composés latences Bizarrement
**Plusieurs appels LLM semblent lents au début, mais comme la mémoire RAG se remplit, vous frappez plus souvent les solutions en cache, et l'ensemble du système s'accélère.**C'est contre-intuitif mais observable.
Essaie toi-même.
**Tout est open source et fonctionne localement sur Ollama:**Avertissement :
C'est un code expérimental.
**Ce n'est pas prêt pour la production.**Ce n'est même pas "bon code" prêt.
Mais c'est une expérience fascinante dans ce qui est possible lorsque vous combinez des algorithmes évolutifs avec des systèmes LLM multi-agents.
Ce que cela signifie en fait
Retirons-nous des détails techniques et posons la question inconfortable :
Qu'est-ce qu'on a construit ici ?
En surface, c'est un système de génération de code.
Vous demandez une fonction, elle en génère une, la stocke et la réutilise plus tard.
Mais ce n'est pas vraiment ce qui se passe.
Ce qui se passe, c'est
—non métaphoriquement, mais littéralement.
What Works ✓
What's Rough ✗
What's Just Weird 🤔
Cinquième partie:
Pression évolutionnaire → Culture et traditions
Le système développe des "préférences" — certains outils pour certaines tâches, certains modèles pour certains problèmes.
J'ai appris.
Sixième partie:
Pourquoi pas au niveau planétaire ?
Je dis que le gradient est continu de "évoluer une fonction" à "évoluer une civilisation".
Et c'est... troublant.
Ce qui fonctionne réellement (Soyons honnêtes)

Le planificateur (surveillant) peut maintenant :
- LLM génère du code Python en utilisant l'API avec la gestion des erreurs
Exécution
Le système intègre des outils exécutables pour une validation complète:
Outils d'essai disponibles en production :
pylint
- Vérification du style PEP 8 et analyse de la qualité du codeMypie
- Contrôle statique de typeFlacons8
- Contrôle de style et détection d'erreursnoir
- Validation du formatage du codeBanditisme
- Numérisation de la vulnérabilité en matière de sécuritépytest
- Exécution d'essais unitaires avec couvertureradon
Analyse de complexité (complexité cyclomatique, indice de maintenance)
vautours
estort
Intégration future des outils :
Validation visuelle
Puppeteer + modèles de vision pour la conception web
Profil des performances
Contrôle de conformité
Services de domaine
Géocodage, enrichissement des données, etc.
**6.**Flux de travail des enfants optimisés par les bords
**Que faire si les workflows pourraient générer des versions optimisées d'eux-mêmes pour les environnements encombrés de ressources?**L'optimisation des bords permet :
Flexibilité de déploiement- Même workflow, plusieurs profils de ressources
Simplification automatique- Le système apprend ce qui peut être taillé
Réglage spécifique à l'appareil
Garde-corps et contraintes de sécurité
À mesure que le système devient plus autonome, nous avons besoin de mécanismes de sécurité robustes pour l'empêcher de faire des choses nuisibles.
Les garde-corps fournissent:
Sécurité du réseau
- Détection PII, balayage secret, prévention de l'exfiltration
Pourquoi cela importe-t-il?
Au fur et à mesure que le système devient plus autonome par l'évolution, il pourrait théoriquement :
Evolve code qui supprime les fichiers importants pour "optimisation du stockage"
Chaque opération — écriture de fichier, appels réseau, exécution de code, transmission de données — doit passer par les garde-corps avant l'exécution.
Le système devrait être sûr par défaut, pas sûr en espérant qu'il ne fait pas quelque chose de dangereux.
Les idées sauvages (les trucs vraiment amusants):
pollinisation croisée
Noeuds de domaines différents apprenant des mutations les uns des autresÉvolution de l'adversaire
Deux agents en compétition pour trouver des vulnérabilités dans le code de l'autre
Méta-évolution
Apprentissage collaboratif
Laboratoires de recherche synthétiques
Chaînes d'outils autonomes
- Le système découvre et intègre automatiquement de nouveaux outils
Cette dernière est liée aux idées de consensus mondial de la Partie 6.
L'architecture est domaine-agnostique:
Approche des plans de surveillance
Outils pour groupes électrogènes
L'exécuteur tourne dans le bac à sable
L'évaluateur note la condition physique
Le système évolue
Remplacer "code" par:
Contrats juridiques
Stratégies d'entreprise
Politiques sociales
- Générer des propositions, simuler des effets, évaluer par rapport aux objectifs, évoluer
Ce n'est PAS :
AGI ou quoi que ce soit de procheSensible ou conscient
Capable de raisonnement général
Un remplacement pour les développeurs humains
C'est :
Un système évolutif pour les artefacts de code
Un workflow multi-agents avec mémoire
Un réseau d'optimisation auto-améliorant
Un prototype pour l'évolution synthétique dirigée
Ils révèlent ce qui est possible. Et ce qui est possible ici, c'est un système qui : Tire des leçons de l'expérience

vers les objectifs
DSE est ma tentative désordonnée, expérimentale, codée par vibe pour construire ça.
Ce n'est pas prêt pour la production.
Ce n'est même pas "bon code" prêt. (Je ne suis pas un développeur de Python, comme quiconque lit la source le remarquera immédiatement.) #AI #MachineLearning #CodeGeneration #Ollama #RAG #EvolutionaryAlgorithms #LLM #Qdrant #Python #EmergentIntelligence #DirectedEvolution
