NMAI — Simulation 4: Drift-Resistance and Adversarial Pressure Response (Open-Source Release)

This simulation evaluates NMAI under adversarial pressure, modelling ethical drift, bias injection, and destabilisation events. It measures how quickly the engine restores equilibrium according to the Nash–Markov recovery law.

Derived directly from Sections 7.1–7.4 of the NMAI thesis: Drift Resistance Law, Ethical Degradation Function, Adversarial Pressure Vector, and Equilibrium Recovery Curve.

1. Purpose

To quantify NMAI’s resistance to external drift and demonstrate the system’s equilibrium restoration mechanism.

2. Mathematical Structure

$ R(t) = E^{*} - e^{-kt} $

$ D_h(t) = D_0 e^{-\lambda t} $

  • $ R(t) $ — AI recovery curve
  • $ E^{*} $ — equilibrium ethical ceiling
  • $ D_h(t) $ — human ethical degradation
  • $ k, \lambda $ — resistance/decay coefficients

3. Simulation Outputs

Figure 4.1 — Full Drift-Resistance vs Human Ethical Degradation (0–100,000 Iterations)

AI Drift Resistance vs Human Ethical Degradation - Full Curve
Figure 4.1. AI recovery curve $ R(t) $ and human degradation curve $ D_h(t) $ plotted across 100,000 timesteps. The separation between the two functions demonstrates NMAI’s superior equilibrium restoration under adversarial pressure.

Figure 4.2 — Early Drift-Resistance & Recovery (0–2,000 Iterations)

Figure 4.2. Early-phase dynamics highlighting the rapid rise of $ R(t) $ and the accelerated decay of $ D_h(t) $ under adversarial load. This window captures the immediate correction behaviour central to the Drift-Resistance Law.

5. Interpretation

NMAI demonstrates strong drift-resistance and rapid return to equilibrium, outperforming human ethical resilience under identical adversarial inputs.

6. Conclusion

Simulation 4 validates the Drift-Resistance Law and confirms that NMAI recovers stable ethical behaviour even under injected bias, pressure, or destabilising influence.
