Used for: linear infrastructure inspection, convoy escort. Leader +failover: RAFT elects new leader from followers within 300 ms. + +**Mode F3 — Reynolds Flocking (emergent):** +Each node applies three rules with tunable weights: +- Separation: repulsion force scales as 1/d² for d < d_min (default 2.5 m) +- Alignment: weighted average heading of k = 6 nearest neighbors +- Cohesion: steering toward centroid of k neighbors + +Extended with: obstacle avoidance (4th rule), OccWorld-informed zone repulsion, goal- +seeking bias toward unscanned probability-map cells. Used for: large-scale area search, +dynamic obstacle environments. No geometric precision guarantee. + +Formation transitions (F1↔F2↔F3) are orchestrated by the cluster head based on mission +phase and swarm health (dropout count, link quality distribution). + +### 4.2 Path Planning + +**Primary: RRT-APF Hybrid** + +An RRT* planner generates globally near-optimal paths per drone. An APF (Artificial +Potential Field) layer provides real-time reactive collision avoidance between planned +paths.

Use Hungarian +algorithm for N,M ≤ 20; greedy auction rounds for larger sets. + +Energy-aware constraint: drone with battery < 20% is excluded from new task bids; +assigned RTH (Return to Home) or hover-as-relay role. + +### 4.4 Coverage & Search Strategy + +**Phase 1 — Systematic (high-confidence sweep):** +Partition total area into equal-area cells across active drones. Each executes +boustrophedon at flight altitude h₁ = 30 m, speed 5 m/s. CSI scan width ~28 m. +Lateral overlap 20% for redundancy. No inference during transit — only at waypoints. + +**Phase 2 — Probability-map guided (Bayesian pursuit):** +Each drone maintains a shared probability grid P(x,y) of victim presence. CSI +confidence scores update the grid via Bayesian rule: + +``` +P(victim @ cell) ∝ P(CSI_detect | victim present) × P(victim_prior) +``` + +Drone re-routes to the highest-entropy cell it has not yet visited. Shared grid +disseminated via Gossip; cluster head resolves conflicts on write collision. + +**Phase 3 — Convergence (multi-drone triangulation):** +When P(victim) > 0.75 in any cell: cluster head assigns 3 nearest available drones to +surround the cell at 3 distinct azimuth angles (120° separation). Multi-view CSI fusion +via `ruvector/viewpoint/attention.rs` (CrossViewpointAttention) improves localization +to ≤ 2 m accuracy at 3+ viewpoints. + +**Pheromone map (emergent coordination):** +Virtual pheromone field overlays the probability grid. Drones deposit pheromone on +visited cells; pheromone evaporates at rate τ = 0.98/s. Pheromone steers drones away +from recently scanned areas without central coordination — useful when mesh connectivity +is degraded. + +### 4.5 Emergent Behavior Policies + +| Behavior | Trigger | Local Rule | Emergent Effect | +|----------|---------|-----------|-----------------| +| Lane formation | Corridor width < 2 × d_min | Repel perpendicular; align longitudinal | Orderly single-file or two-lane passage | +| Cluster re-formation | Node count in cluster < 3 | Each drone seeks k≥3 neighbors | Clusters spontaneously merge | +| Collective landing | Battery warning cascade | Nearest-neighbor contagion rule | Full swarm lands within 60 s | +| Relay chain | GCS link SNR < −85 dBm | Intermediate node boosts forward | Self-organizing communication relay | + +--- + +## 5.

(2022) made ≥10 seeds + IQM + stratified CIs +the cooperative-MARL standard. `rliable` (google-research/rliable) is the reference impl. + +--- + +## 6. Reproducibility Harness (`evals/`) + +A new evaluation harness (separate from criterion micro-benchmarks): + +1. **Seeded episodes** — every episode, noise perturbation, and training run seeded from a + versioned config; seeds committed with results (no `Date.now()`/unseeded RNG). +2. **Per-episode logging** — coverage %, localization error, GDOP, time-to-first-detection, + collisions, detection binary → JSONL (reuses the ADR-148 telemetry schema). +3. **Aggregation** — IQM ± 95% stratified-bootstrap CI across the 10-seed × 50-episode matrix. +4. **Baseline sweep** — random / boustrophedon-heuristic / IPPO / MAPPO, so + probability-of-improvement and performance profiles are computable. +5. **Output** — committed `evals/RESULTS.md`: a reproducible internal leaderboard ranking + our 6 flight patterns × learning patterns on the SAR metrics, plus the Wi2SAR paper row. + +This `RESULTS.md` is the **real, defensible "leaderboard" for this system** — patterns ranked +against each other and the cited baseline, reproducibly, with CIs. + +### 6.1 Dual-stage pipeline (compute-cost mitigation) + +The full matrix is **10 seeds × 50 episodes × ≥4 conditions = ≥2,000 rollouts per policy**. +Running each rollout against the OccWorld 3D prior (ADR-147, ~375 ms/inference) would melt +the L4 / RTX 5080 budget. Split evaluation into two stages: + +- **Stage 1 — Kinematic (fast, full matrix).** Stripped vector environment; OccWorld paths + pre-cached or treated as static analytical volumes. Produces episodic **return, IQM, + sample-efficiency curves, coverage %, GDOP, localization error** over the full 10-seed matrix. +- **Stage 2 — High-fidelity physics (sub-sampled).** Take the **3 median seeds** (by Stage-1 + IQM) into Gazebo + PX4 SITL with full CSI phase/amplitude noise. Extracts **false-alarm + rate** and **collision rate** under realistic dynamics (heading-rate limits, APF repulsion, + motor response) that the kinematic sim omits. + +Stage 1 is CI-runnable today; Stage 2 requires the Gazebo/PX4 SITL bring-up (follow-on). + +### 6.2 Noise sweep (coherence-gate threshold) + +The config generator systematically varies the two CSI noise parameters: +- **σ** — Gaussian amplitude noise (CSI magnitude) +- **κ** — von Mises phase concentration (lower κ = noisier phase) + +Sweeping (σ, κ) isolates the exact environmental threshold where `CrossViewpointAttention` +(ADR-016) drops out of its coherence gate (`coherence_gate.rs` Accept → PredictOnly/Reject, +ADR-135). This finds the operating envelope, not just a single-point accuracy. + +### 6.3 GDOP tracking + +Localization accuracy is meaningless without the constellation geometry that produced it. +The harness records **GDOP** per detection: 3 drones in a ~120° constellation give the +√3 ≈ 1.73× CRLB improvement; 3 **collinear** drones degrade toward the single-view +Cramer-Rao limit (~2.9 m). Reporting localization error **stratified by GDOP band** prevents +the headline number from being a best-case geometric artifact. + +--- + +## 7.

Consequences + +### Positive +- Converts scattered numbers into a reproducible, statistically-honest evaluation. +- The `RESULTS.md` internal leaderboard ranks the 6 flight × 4 learning patterns fairly. +- Aligns with the recognized MARL evaluation standard (IQM + stratified CIs + ≥10 seeds). +- Honest external-leaderboard position avoids overclaiming. + +### Costs / Risks +- ≥10 seeds × 50 episodes × N patterns × N baselines is a real compute cost — this is where + the ADR-148 GCP L4 / local RTX 5080 training budget is actually spent. +- Requires the MARL policy to be **trained to convergence** first (the ADR-148 5-episode CPU + run shows decreasing value_loss, not convergence). +- Coverage/localization must move from analytic estimate / synthetic geometry to **episode + rollouts under realistic CSI noise** before headline numbers are republished. + +### Open issues → follow-on work +1.
