Act I — The Human Story & Historical Turning Point (M.03)
Every child who has played the card game SET knows the rule: each card has four features (number, shape, shading, color) with three choices each, and a 'SET' is three cards where each feature is either all the same or all different. Mathematically, the 81 cards form the four-dimensional affine space F_3^4 over the three-element field {0, 1, 2}, and a SET is simply a line x + y + z = 0 (mod 3). In 1971, Giuseppe Pellegrino proved that in 4 dimensions you can pick at most 20 cards without forming a line. Such a line-free collection is called a Cap Set.
For 45 years, one of the flagship open problems in Ramsey theory and additive combinatorics was the Cap Set Problem: as the dimension n grows, does the maximum size of a line-free subset S in F_3^n grow like 3^n, or exponentially slower like c^n for some c < 3? In May 2016, Ernie Croot, Vsevolod Lev, and Péter Pál Pach—followed within days by Jordan Ellenberg and Dion Gijswijt—stunned the mathematical world with a two-page polynomial-method proof that |S| <= 3 * (2.7551)^n. Then, in December 2023, Google DeepMind's FunSearch paired a Large Language Model with an evolutionary program evaluator to discover a brand-new priority function constructing a 512-element Cap Set in F_3^8 (improving capacity to >= 2.1810), followed by AlphaEvolve's 2025 discovery of a rank-48 decomposition for 4x4 complex matrix multiplication—beating Volker Strassen's 1969 recursive bound (7^2 = 49) for the first time in 56 years.
FunSearch did not hand mathematicians an inscrutable black-box list of 512 vectors; it evolved a short, human-readable Python priority function whose symmetries taught humans a new way to build cap sets.
Momentos decisivos
| Año | Hito |
|---|---|
| 1969 | Volker Strassen — Discovers 2x2 matrix multiplication in 7 scalar multiplications (49 for 4x4 via 2-level recursion). |
| 1971 | Giuseppe Pellegrino — Proves the maximum Cap Set in F_3^4 (the game SET) has exactly 20 points. |
| 2016 | Croot-Lev-Pach & Ellenberg-Gijswijt — Solve the Cap Set conjecture via slice-rank polynomial method: |S| <= 3 * (2.755104)^n. |
| 2023 | Google DeepMind FunSearch — Discovers an explicit 512-cap in F_3^8 (DOI: DOI 10.1038/s41586-023-06924-6 [Scite ↗]) by evolving Python priority functions. |
| 2025 | Google DeepMind AlphaEvolve — Finds an exact rank-48 bilinear tensor decomposition for 4x4 complex matrix multiplication (48 < 49). |
Act II — How It Actually Works: Plain-Language Intuition to Governing Law (M.03)
Why is searching directly for a 512-point subset inside F_3^8 = 6,561 points utterly hopeless? Because the number of subsets of size 512 is roughly 10^780—vastly larger than the 10^80 atoms in the observable universe. Any brute-force or Monte Carlo search over raw coordinates drowns immediately. Live parameter coupling: n = 8 under governing law .

Tres experimentos para probar
- Experiment 1 (Compare Upper & Lower Bounds): Step through Stages 1 -> 4 to see how the polynomial method ceiling (2.7551^n) and FunSearch evolutionary floor (2.1810^n) bracket the true capacity of F_3^n.
- Experiment 2 (Inspect the Rank-48 Tensor Breakthrough): Examine the SVG comparison plate below showing how reducing 4x4 multiplication from 64 (naive) -> 49 (Strassen 1969) -> 48 (AlphaEvolve 2025) lowers the asymptotic exponent to log_4(48) = 2.79248.

Act IV — Extending Human + AI Potential & Frontier Discovery
The deepest lesson of FunSearch and AlphaEvolve is interpretability through code. When an AI outputs a 15-line Python scoring function rather than a neural network weight matrix, human mathematicians can read the code, spot a hidden reflection symmetry, and generalize the construction to higher dimensions.

## 2. Deterministic Verification & Falsification Rules
1. Verify Cap Set three-term progression avoidance: for all distinct x, y, z in S subset F_3^n, x + y + z != 0 (mod 3).
2. Enforce Ellenberg-Gijswijt slice-rank upper base ((1 + 2*theta)/theta^(2/3)) = 2.755104 vs FunSearch F_3^8 lower bound |S| >= 512.
3. Verify bilinear tensor decomposition sum_{r=1}^R (u_r . A)(v_r . B) w_r = A B exactly satisfies all n^6 Brent equations.
## 3. 4-Stage Physical & Mathematical Mechanism
- Stage 1 (Affine Line-Free Constraint): A subset S ⊂ F_3^n is a Cap Set if no three distinct vectors x, y, z ∈ S satisfy x + y + z = 0 (mod 3).
- Stage 2 (Croot-Lev-Pach & Ellenberg-Gijswijt Polynomial Method): Vanishing slice rank of the indicator polynomial bounds |S| ≤ 3 · (2.755104)^n.
- Stage 3 (FunSearch Priority-Function Discovery): Evolutionary LLM search over Python priority functions constructs an explicit 512-vector cap set in F_3^8.
- Stage 4 (AlphaEvolve Rank-48 Tensor Decomposition): Beats Strassen's 1969 2-level recursion (7² = 49) by discovering a 48-product decomposition for 4×4 complex matrices.

DOI 10.1038/s41586-023-06924-6), DeepMind's FunSearch paired an LLM with a deterministic verifier to construct a 512-vector Cap Set in F_3^8 beneath the Ellenberg–Gijswijt slice-rank ceiling (2.7551^n, Annals of Math. DOI 10.4007/annals.2017.185.1.8), while AlphaEvolve discovered a Rank-48 tensor decomposition for 4x4 complex matrix multiplication—directly informing non-immunogenic synonymous CFTR mRNA codon packing.
