Module floating_zone 

Greedy coordinate-descent (floating-zone) search for high-error points.

The floating-zone walk is the strongest global pivot search used in this codebase: from a starting point it repeatedly sweeps every site coordinate, moving each coordinate to the value with the largest interpolation error, until the error stops improving or exceeds a tolerance. It is a strict generalization of the single-cross search used elsewhere (one sweep with no repeats equals a cross scan).

Enums

FloatingZoneError

Invalid search inputs or an error from a floating-zone evaluator.

Functions

floating_zone_walk

Walk one floating-zone search trajectory.

floating_zone_walk_with_initial_error

Walk a floating-zone trajectory using an already evaluated starting error.
