Gödel Machine Skill

"A Gödel Machine can rewrite any part of itself, including the learning algorithm, provided it can first prove that the rewrite is beneficial." — Jürgen Schmidhuber

Overview

The Gödel Machine is a self-improving system that:

1. Contains a formal proof system (e.g., Lean4, Coq)
2. Has a utility function defining "better"
3. Can rewrite any part of itself if it proves the rewrite improves utility
4. The proof constraint prevents reckless self-modification

Darwin Gödel Machine (DGM)

Combines evolutionary search with formal proofs:

class DarwinGodelMachine:
    """
    DGM: Open-ended evolution of self-improving agents.
    
    Archive of agents, LLM-based mutation, fitness evaluation,
    keep if novel and beneficial.
    """
    
    def __init__(self, initial_agent: Agent, prover: TheoremProver):
        self.archive = [initial_agent]
        self.prover = prover
        self.generation = 0
    
    def evolve_step(self) -> Agent:
        # Sample parent from archive (fitness-proportionate)
        parent = self.sample_archive()
        
        # LLM-based mutation
        child = self.llm_mutate(parent)
        
        # Evaluate on benchmarks
        fitness = self.evaluate(child)
        
        # Optionally: verify improvement formally
        if self.prover.can_prove(f"utility({child}) > utility({parent})"):
            child.proven = True
        
        # Add if novel and good
        if self.is_novel(child) and fitness > 0:
            self.archive.append(child)
        
        return child
    
    def llm_mutate(self, agent: Agent) -> Agent:
        """Use LLM to generate improved version."""
        prompt = f"""
        Current agent code:
        {agent.code}
        
        Current fitness: {agent.fitness}
        
        Suggest an improvement to make this agent better.
        Return only the improved code.
        """
        
        new_code = self.llm.generate(prompt)
        return Agent(code=new_code, generation=self.generation + 1)

Key Properties

1. Halting Problem: Cannot prove all beneficial rewrites (incompleteness)
2. Safety: Only rewrites with proofs are applied
3. Bootstrapping: Initial prover must be trustworthy
4. Asymptotic Optimality: Converges to optimal policy (given enough time)
