Scenario: large-scale¶
Class: large / mobile

Provenance — regenerated on every merge. Unlike the sweep pages, this table is not pinned to a release:
benchmarks.ymlre-runs the discrete taxonomy on every merge to the default branch and rewrites the generated block below, so these numbers track the current tip ofmainand already include the pheromone-weighting change (#327) and the per-seed RNG stream assignment (#352). They are a per-merge regression signal at the 10-run publication floor (#318); the release-pinned, 20-seed numbers live on the sweep and headline pages. See Provenance and #365.
What it stresses¶
100 nodes. The paper base scenario grown in both node count and terrain, so paths get longer and control traffic has more nodes to reach — the discrete counterpart of the scale sweep.
Configuration¶
| nodes | area long edge (m) | max speed (m/s) | pause (s) | flows | propagation |
|---|---|---|---|---|---|
| 100 | 2100 | 20 | 30 | 20 | range |

workflow runs the taxonomy with --quick.
Results¶
Caveat —
large-scaleandheavy-loadcurrently reflect an open defect. #173 (P1, open): withenableMultipathon, reactive forward ants are bounded neither by a broadcast budget nor by(src,seq)duplicate suppression, so route discovery floods combinatorially in dense graphs. Read those two rows as a bug report, not as protocol character. See docs/fidelity.md.
