Struct FirstLastStepScoreImprovingForager 

pub struct FirstLastStepScoreImprovingForager<S>
where
    S: PlanningSolution,
{ /* private fields */ }

A forager that picks the first accepted move that improves on the last step’s score.

Once a move with a score strictly better than the previous step is found, the forager quits immediately and selects that move. If no such move exists, it falls back to the best among all accepted moves.
