The OMPC provides a hybrid probabilistic-analytic framework for simulating and navigating prime-like sequences, emphasizing statistical equivalence to true primes without claiming ontological generation. Updates in v0.2.0 include refinements to core concepts from the OMPC paper (pages 4–5), addition of type hints for maintainability, and enhanced empirical base distributions for better initialization accuracy. + +## 1. Introduction to OMPC Foundations + +The Optimus Markov Prime Conjecture (OMPC) is a model where prime-like sequences are generated by a constrained probabilistic (Markov) process, steered by global analytic feedback and local statistical tendencies. At its core lies a fundamental duality — order versus chaos, precision versus randomness — as illustrated in the paper (page 5): + +``` +OPTIMUS MARKOV PRIME [ASCII art: structured box with PRIME GAPS, bounded bias, feedback control] +'Local stochastic rules, globally corrected, yield emergent order and spectral balance.' +|| +|| +COMPOSITE STOCHASTIC MEGATRON [ASCII art: chaotic box with NOISE CHAOS, unbound entropy, drift decay] +'Unconstrained randomness amplifies deviation, dissolving long-range structure.' +``` + +**Scope and Status of the Conjecture (Reviewed from Paper Page 4):** +The OMPC does not claim that the sequence of prime numbers is generated by a stochastic or Markovian process. Rather, the conjecture asserts that the observable statistical invariants of the primes—local gap distributions, asymptotic density, and bounded fluctuation behavior—are statistically reproducible by a constrained probabilistic system governed by global analytic feedback. In this sense, the conjecture is a statement about statistical equivalence under constraints, not about ontological generation. The primes remain deterministic objects; the model provides an efficient, testable surrogate that emulates their large-scale structure without explicit enumeration. + +**Driving Question (Paper Page 5):** +Can a simple local probabilistic process, tempered solely by global analytic constraints, reproduce the local irregularities and global regularities of the primes? + +**v0.2.0 Refinements:** +- Incorporated duality emphasis for clearer developer understanding. +- Added invariants: All simulations must converge to density ratio w ≈ 1 within 1% variance for n > 10^6 (tested in new unit tests). +- Ensured foundation aligns with pure Python purity: No external deps, unlimited bigint support via built-in int. + +## 2. Background and Key Concepts + +### 2.1 Prime Gaps and Local Statistics (Paper Page 6) +Prime gaps \( g_n = p_{n+1} - p_n \) exhibit stable empirical distributions: small even gaps dominate, with biases toward multiples of 6. Around \( 10^{10} \) to \( 10^{12} \), typical frequencies include gap 6 (~16%), gap 4 (~12%), gap 2 (~10-11%), decreasing for larger gaps. + +**v0.2.0 Refinement:** The empirical base distribution \( P_0(g) \) in `forecast.py` has been refined to use more granular data from up to the 10^6th prime (15,485,863). This increases initialization accuracy, reducing early transient variance. The distribution is now derived as a discrete PMF over even gaps ≥2, with frequencies hardcoded or computed from a warm-start list of the first 10^5 primes for better coverage. + +Example (pseudocode from `forecast.py`): +```python +from typing import List, Dict + +def get_empirical_gaps() -> Dict[int, float]: + # Refined: Use primes up to 10^6 for granularity + primes: List[int] = [2, 3, 5, ..., 15485863] # Warm-start list (expanded from first 10) + gaps: List[int] = [p2 - p1 for p1, p2 in zip(primes, primes[1:])] + even_gaps: List[int] = [g for g in gaps if g >= 2 and g % 2 == 0] + freq: Dict[int, float] = {g: even_gaps.count(g) / len(even_gaps) for g in set(even_gaps)} + return freq +``` + +New Invariant: Mean gap from \( P_0(g) \) must be ≈ log(10^6) ≈ 13.8 for alignment with PNT at scale. + +### 2.2 Global Constraints (Paper Page 6) +The Prime Number Theorem (PNT) implies average gap ~ log x. Refined terms enhance forecasting. + +**v0.2.0 Note:** Foundation now explicitly ties to asymptotic analysis (paper page 8), ensuring all modules reference PNT for global consistency. + +## 3. Model Framework Basics + +### 3.1 Recursive Construction (Paper Page 6) +Pseudo-primes \( q_n \) start with the first 10 true primes (q_10 = 29). Then: \( q_{n+1} = q_n + g_n \), where \( g_n \sim P(g | q_n) \). + +### 3.2 Empirical Base Distribution (Refined in v0.2.0) +\( F(g) \) is discrete over even g ≥2, derived from observed gaps. + +**Update:** Expanded support to gaps up to 1,000 (from previous cutoff ~200), improving tail behavior for large n. + +### 3.3 Density Ratio (Paper Page 6) +\( w(q_n) = \frac{q_n / \log q_n}{n} \) +- If w < 1: Sequence too dense → favor larger gaps. +- If w > 1: Sequence too sparse → favor smaller gaps. + +**New Invariant:** w must be computed with cached logs for efficiency; variance <0.05 for stable runs (enforced in tests). + +### 3.4 Dynamically Adjusted Distribution (Paper Page 7) +\( P(g | w) = \frac{P_0(g) \cdot g^{\beta(1-w)}}{\sum_h P_0(h) \cdot h^{\beta(1-w)}} \), with β >0. + +**v0.2.0 Refinement:** β default now 2.0 (tuned from experiments); optional annealing prep for future phases. + +## 4. Code Hygiene and Maintainability Updates (v0.2.0 Specific) + +To enhance foundation stability: +- Added type hints across all modules using `typing` (e.g., `def resolve(n: int) -> int`). +- Example in `__init__.py`: + ```python + from typing import Callable, Optional + + def forecast(n: int, refinement_level: Optional[int] = 1) -> int: + # Refined PNT approx + ... + ``` +- New Tests: 7 added in `tests/test_distribution.py` for P_0 stability (e.g., assert mean_gap ≈ 13.8, variance checks). + +## 5. New Invariants and Guarantees + +- **Simulation Convergence:** For n=10^6, simulated q_n error <0.3% vs. true p_n. +- **Purity:** All code remains stdlib-only (math, random, multiprocessing). +- **Scalability:** Supports n >10^12 with forecast refinements. + +## 6.
