- Worth noticing
- Route search keeps the best route per sequence within 15% of the best, then refines candidates with seeded SADE workers.
Field notes
The plot controls cover origin, destination, departure range, flight time, and color scale; users can pan, zoom, reset, or click a planet to inspect its orbit. Route search accepts flyby sequences such as VVEJ or EVVEJS, with M denoting Mars and Me Mercury. The page describes a two-stage process: a flyby-only search followed by seeded SADE refinement, with results re-sorting as workers finish.
