The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

On CEC 2017, DVO achieves the best mean log10 error on 34 of 58 cases and the best Friedman average rank (1.67), and is significantly better than every baseline under Holm-corrected Wilcoxon tests.

C2weakest assumption

That the specific combination of vortex-law regularization, three-phase switching thresholds, and basin-assignment rules produces a genuine advantage that will hold on problems outside the CEC collections used for tuning and validation.

C3one line summary

DVO models optimization particles with a three-phase vortex update rule and outperforms several baselines on CEC 2017 benchmarks while using a calibration-validation split.
