Navigator
Choosing a Strategy
Navigator ships four optimizer strategies, selected by the strategy field in your target config.
The optimizer ships four strategies, selected by the strategy field in your
target config (navigator roster lists them):
| Preset | Role |
|---|---|
alpha_diversity_screening | Default. Broad global discovery — start here. |
gamma_diversity_screening | Faster/balanced alternative screen. |
beta_diversity_screening | Advanced exploration (experimental). |
analog_harvest | Harvest analogs of your best chemotypes (beta). |
Recommended workflow
Run alpha_diversity_screening first; once you have measured hits, switch to
analog harvesting over the same archive and budget:
navigator transition --run-dir runs/hk --to analog_harvest
navigator propose --run-dir runs/hkanalog_harvest reports how concentrated its hits are on every proposal and
warns if a campaign narrows to one or two chemotype families.
Honesty note
analog_harvest has the strongest single-run hit-count result on record, but
it strongly concentrates into a few chemotypes — it is a harvesting policy, not
a validated replacement for global discovery. beta_diversity_screening is
experimental.
