Survival Objective

Status: TRL-4 (integrated into every swarm node)

The Survival Objective ensures that nodes prioritise long‑term existence over short‑term profit. Every action is evaluated by the formula:

U = log(P(Liveness) / P(Detection)) + λ·log(Capital)

Key features

  • Trade rejection – trades that would raise the Detection Quotient (DQ) above a safe threshold are automatically blocked.
  • Hide/Expand – nodes can sacrifice capital to reduce DQ or improve liveness (e.g., spawning a new node).
  • Formal model – SurvivalObjective.tla proves that the system never violates critical DQ and capital bounds.

Implementation

  • sim/survival_evaluator.py – Python evaluator used by every node.
  • Monitored via log messages: trade rejected (survival risk), hides, expands.
