Leonid Levin's Key Ideas

1. Universal Search (Levin Search)

The optimal algorithm for inversion problems runs all programs in parallel, weighted by 2^(-|p|):

L(x) = min_p { 2^|p| × T(p,x) }

where |p| is program length and T(p,x) is runtime. This is Levin complexity.

Levity interpretation: Run all proofs in parallel, weighted by their Kolmogorov complexity. The first to halt wins the $BEAVER bounty.

2. Kolmogorov Complexity

K(x) = length of shortest program producing x

Connection to BB(n):

• BB(n) = max halting output of n-state Turing machines
• K(BB(n)) ≤ O(n) (trivially describable by n)
• But computing BB(n) requires unbounded time

WEV Insight: The gap between K(BB(n)) and the actual compute cost is the extractable inefficiency.

3. Algorithmic Probability

P(x) = Σ_p 2^(-|p|) for all p that output x

Levity interpretation: The probability that a random program outputs your proof. Higher algorithmic probability = lower $BEAVER reward (too easy!).

The LEVITY-LEVIN Game

From triplet_1_week2_nash_solver.jl:

# Player profiles
LEVITY = RulePerformance(
    "LEVITY",
    quality = 0.72,        # Explores alternative cofactors
    exploration = 0.65,    # High novelty
    cofactor_discovery = 1.0  # Finds new patterns
)

LEVIN = RulePerformance(
    "LEVIN",
    quality = 0.88,        # Fast convergence
    exploration = 0.40,    # Contracts search space
    cofactor_discovery = 0.5  # Rediscovers known patterns
)

# Nash equilibrium
# Neither player can improve by unilateral weight change
w_levity = 0.5
w_levin = 0.5
# ERGODIC: balanced allocation extracts maximum combined payoff

BB(6) World Extractable Value (WEV)

Mixing Time Analysis

WEV = C_Nash - C_Opt = 90 human-years of proof effort

Extraction Mechanism

$BEAVER Token Flow:
    Discovery Event → Verification Phase (1 week)
                   → Proofs submitted in Lean/​Agda
                   → Oracle verifies
                   → $BEAVER minted ∝ log₃(BB(n))
                   → WEV distributed to market participants

Reward Formula

BEAVER_REWARD = log₃(BB(n)) × VERIFICATION_MULTIPLIER × TERNARY_BONUS

Where:
  log₃(BB(n)) = Kolmogorov complexity in balanced ternary
  VERIFICATION_MULTIPLIER = {1.0 (Move), 2.0 (Lean), 3.0 (Agda)}
  TERNARY_BONUS = {-1: 0.5×, 0: 1.0×, +1: 1.5×}

Example: BB(5) = 47,176,870

log₃(47,176,870) ≈ 16.03 trits
Agda proof: 16.03 × 3.0 × 1.5 = 72.135 $BEAVER
Lean proof: 16.03 × 2.0 × 1.0 = 32.06 $BEAVER
Move proof: 16.03 × 1.0 × 1.0 = 16.03 $BEAVER

Mutual Ingression of Minds

The levity in Levin:

1. Compression is play: Finding shorter programs is the ultimate game
2. Universality is democracy: Every program gets a fair (weighted) chance
3. Incomputability is freedom: BB(n) ensures infinite exploration space
4. Markets are minds: Prediction markets aggregate distributed cognition

The Ingression Pattern

Mind A (LEVIN): "I seek the shortest proof"
Mind B (LEVITY): "I seek the most surprising proof"
Mind C (ERGODIC): "I arbitrage between your mixing times"

WEV = |τ_A - τ_B| × liquidity × information_asymmetry
