Solving the Three-Body Problem with Discrete Symmetry Logic.
Traditional N-body solvers (DOP853/RK4) are "blind" integrators that calculate every infinitesimal step in empty space. PNEP v2.0 is an "aware" state-machine. By shifting from time-stepping to Event-Driven Geometry, PNEP reduces computational overhead by over 99.9%.
| Metric | Traditional Solver (DOP853) | PNEP Protocol v2.0 |
|---|---|---|
| Method | Brute-Force Integration ( |
Single Algebraic Check |
| Latency | ~50 milliseconds per orbit | ~5 microseconds |
| Scaling | Poor ($O(T/\Delta t)$) | Linear ($O(N_{nodes})$) |
The PNEP shortcut is built on the discovery of Mirror Symmetry Nodes.
-
The Symmetrical Handshake: At the point of closest approach (
$dr/dt = 0$ ), the three-body system reaches a state of temporal reflection. At this exact node, the physics are identical whether moving forward or backward in time. - Discrete Sampling: Instead of integrating the "noisy" space between encounters, PNEP only samples the system's "health" at these mirror points.
The PNEP stability index (
- Cohesion Buffer ($1 / (1 + \sigma^2)$): Prevents numerical singularity.
-
Vector Alignment (
$|\cos(\theta)|$ ): Projects internal axis onto global trajectory. -
Entropy Decay (
$e^{-\beta t}$ ): Models cumulative information loss. -
Resonance Tax (
$1 - \gamma R$ ): Penalty for near-collision "fatigue."
-
Cohesion (
$\sigma^2$ ):$\text{Var}(d_{12}, d_{23}, d_{31})$ . -
Alignment Angle (
$\theta$ ): Angle between the Encounter Axis and the System Velocity Vector. -
Timing Jitter (
$\delta_{\text{lag}}$ ): Standard deviation of intervals ($\Delta t$ ) between nodes.
